Two caption layers can appear when burned-in text and a selectable track coexist, or when TV captions and player subtitles both render. Identify each layer before disabling all accessibility text. Keep the single version that meets your viewing needs. Locate each text source by switching off one caption layer at a time. Similar-looking words can come from different rendering paths, and one layer may be an accessibility track that provides information beyond a translation already present in the picture.
Test selectable tracks
Disable one source of text at a time. Start with the player's selectable subtitle menu and disable its track while observing exactly which text disappears. If one layer remains, check whether it is fixed within the video or produced by another caption system. Re-enable the intended track before testing another control so the comparison stays clear. A bilingual subtitle track can also deliberately contain two languages in one cue, which differs from two independently selectable layers.
Check burned-in text
It remains part of the picture. If text remains with selectable captions disabled, determine whether it belongs to the encoded picture. Burned-in translation cannot be turned off or restyled independently, though a supplied clean edition may be available. Avoid promising that a single subtitle switch removes every visible word. If the selectable layer is hearing-access captions, consider whether disabling it would remove speaker or sound information the viewer needs, even when the remaining burned-in text duplicates some spoken dialogue.
ReviewTV controls
Broadcast caption controls may be independent from the player. Inspect the TV's caption controls only where they apply to the actual input and delivery path; they do not necessarily affect every external player. Test one documented control and note which layer responds. If two local renderers were active, keep the one that provides the required content and readability. Report duplicated source cues separately if the same duplication remains in one track on multiple compatible clients, rather than blaming the provider for a local double-rendering arrangement.

An example to work through
English text is burned into the picture while a secondEnglish subtitle track overlays it. Turning off the player track removes one set of dialogue, while a translation remains fixed in the image. The remaining words are burned in, so a font control cannot remove them; the viewer then decides whether the selectable accessibility track still supplies useful additional sound information.
Questions about this topic
Can all duplicate text be removed?
Burned-in text cannot be switched off. Image-encoded text stays with that edition, while separate layers may be removable.
Is this always a provider error?
Not when two local rendering controls are enabled. Independent TV and player rendering can produce duplication locally, so identify the layers first.
