MOGRT files very buggy and impossible to use with Premiere

Seems that Premiere Pro won't link the motion graphic templates consistently, even if the motion graphic template folder is just two levels from the Premiere project file location, and is also true obviously if that MGTM (motion graphics template media) folder is of its own making. And even if it does link to the motion graphic template (MGT) file, it might appear to be corrupt to the software (?), which clearly isn't the case.

What I have found to work is uninstalling Premiere and reinstalling a previous version of Premiere (which really is inconvenient). Or a better solution that worked for me:  Copy an MGT file to the same level as the project folder (where the Premiere project file is written and stored) without a sub folder. Then you can browse to new MGT location when ready to link it. This process seemed to clear up other, though not all, MGT files that were previously supposedly corrupt.
