Well that doesn't sound right then.
You may need to re-install if something got corrupted somehow. (have you tried reinstalling FPSC yet?)
Make sure you back up all of your custom media before you do.
If you are running the V114 Beta, then you may need to revert back to V113 and report the glitch in the V114 Beta Thread.
Try a reinstall if you haven't already.
But before you do , I have one more question...
Are you using the headshots appear script for the character?
If so, then try using the regular appear script and see if that fixes it.
There is a way to adjust the height of the headshots, but I forget what the command is.
