Just a bizzare bug that I had in one of my projects. 

Magix Movie Edit Pro 2014

I have two movies in different tabs in the program. On one of them the audio functions work fine. In the other, none of the audio effects will apply. I can change things (EQ etc.), load presets etc, but none of it would stick. Seems to be unique to this particular movie as I've not had this issue elsewhere. 

I don't need a solution, just reporting an odd bug.
