Master Completion Slide Showing Wrong Language

I have six-language course with a structure of: opening slide/choose language (Set TFEnglish to value True when user clicks English, etc) --> then the slides for each language --> all leading to a master completion slide with a message on layers for each language. I've added triggers for each layer to show like this: Show English Layer when timeline starts on this slide if TFEnglish = value True.

Problem is that every time I preview the course, each language is ending up on the Japanese layer. I deleted all the triggers and started again. Same result. I know this method works bc I published a successful course like this last year.

Any idea why the triggers are misfiring this way? HELP! I need to publish the LMS very soon!
