Mass Timecode export

I'm a DIT and one of my job duties is to export lowres proxies with timecode burned on for transcription purposes.  So i'm exporting anywhere from 5 to 100+ files at a time.  When i put on the timecode overlay effect over multiple selected files at once using the 'Generate Timecode' option it defaults to 0:0:0:0 on all the clips. I have to go to each file and swap to the 'Media File' option then back to get the proper timecode overlay. Even then sometimes AME doesn't collect the proper timecode.

Am i doing something wrong when trying to apply this overlay to multiple files at a time? Or is this just a 'feature' of the software?
