Allright, quick update. @BR There should be no issue in having an empty tag for the marking according to the code, it is actually accounted for. But, you cannot change the marker in the settings due to an error. I fixed that.
With regards to the other issue with the tagging of the formatting. I have created an alternative method for tagging and I will test this tomorrow on Word 365. It works on Word 2007, but then again so did the original code... If it works, I will utilize the same mechanism for the untagging. Stay tuned.
BTW if you want to add votes to my 'idea' to fix Word, you can add your votes here:
