"Custom" default audio transition time is being overridden.

I have a custom transition time for my audio transitions to 0.06 seconds, so that I can quickly crossfade all of my audio clips at the end of an edit. 

Since I have updated Premiere Pro to 24.2.1 (latest versions always scares me) the custom length is being overridden and what is actually being applied is probably the  Adobe default length. As you will see in the attached screen shots the length of the transition is around 30 frames. 

Has anybody come across this issue before? I would absolutely love to get to the bottom of this before I reach the end of this edit. I don't fancy manually changing all of the crossfade lengths. 

Thanks in advance.
