> AnkiDroid hides the option to set the interval to the same value, as was mentioned in [Set Due Date: Hide 'set interval to same value' if FSRS is enabled](https://forums.ankiweb.net/t/set-due-date-hide-set-interval-to-same-value-if-fsrs-is-enabled/53890).

https://github.com/ankitects/anki/blob/0e31efac08cddf0a43ad0b44f05f2a8e6ef0d91a/ftl/core/scheduling.ftl#L166-L169

This is baked into the translation string. Maybe just remove all "!"s from this string if FSRS is enabled to avoid re-translation work? Although this would still be inaccurate because "sets the interval to 1" isn't true if the card wasn't reviewed the same day as the date was set. Maybe delete the line the "!" Marks are on?

Start by reading ft l/core/scheduling.ftl around lines 166-169 and compare the displayed due-date description with the FSRS behavior described in the issue. Verify the wording no longer advertises the invalid "!" option when FSRS is enabled, while preserving an accurate description for other cases.
