You could try to re-load your cfg if you have a cuztomized cfg, else the one of standard's that you use, if that not work, use the Default, save, close and reopen TC, then try load your preferred cfg again.
If it's not ok, then i think you need to use default and re build it.
You will find the cfg's in Customize/ Options
Another thing to try is to delete the Built-in or do a Repair, NB! TC should be closed if you try this.
