Not sure about the content glitch, but I think I had a similar TC entry problem with the frame value in m364 when assigning a media file a timecode value in the 'Files' tab in the 'Libraries' window..

Work around for this was to enter the TC value manually in the 'MediaFilesPrefs.xml' in your show folder. (Make a Backup first just in case!)

It will look something like below.

<mediaprefs version="0.1">
<media folder="0" file="0">
<overide active="YES" timecode="01:01:01:24" />

Just enter your required TC value for each file where the TC is, save the file and it should work.
