Media encoder 2017 takes different file names from 100fps than from 25 of 50 fps from source P2

Hello,

I'm working on a project rendering proxies daily for two years. We updated the media encoder to be able to render the 100 fps images together with te 25 and 50 fps images. Now it turns out that media encoder 2017 takes a different file name from the source with the 100 fps images. Where it is supposed to say 830HO0RQ it wil use the full source name L220_C074_170107_J40D_M_830HO0RQ from the P2 metadata. Is there a way to export the 100fps files with the same type of name as with the rest of the files?

Thanks!
