i FEEL LIKE i'M TAKING Crazy Pills 7.3

Hello ez009,
If you still have an issue with the file, please send it to our tech. support with the reference to this post and also attach the trimming project file so we could reproduce the issue.

Ok I just tried this with 6.x   and same issue. so I'm not going crazy. Must be a K-Frame issue. Ugh.

Hi. What is going on in 7.3?   I can't seem to trim a file to save my life. Nothing is working.
I used 6.0 from 2016 and just upgraded.  I've re-exported this edit 7 different ways and am not getting an edited output.
I read through the new help file which is relatively straightforward (except there is no "Start Trimming" under the Edit menu.

There is a discrepancy in that the orig file being 912,477kb  and upon exporting selected fragment OR using File->Save Media file As 
It reports that the newly outputted result is 812.xx etc - correctly smaller for the edit - however the resulting file is still the exact same 912,477.

Something is definitely off. This isn't brain surgery.  Pls advise.
