Gost alternate text in the translation document

Articulate Storyline 360 is adding alternate text to the translation document that doesn't exist in the source file. Specifically, the Alt text for "SUBMIT_BT 1" in the translation document changes to "Environmental Risk," even though this text is not present in the current source file.

Notably, "Environmental Risk" was previously the name of a button in another source file from the same course series.

Since slides and interactions are copied and pasted between courses, could there be a software cache that needs to be cleared?
