Map Styles To Tags & Hyperlinks
I have some troubles with the "Map Styles To Tags" function in Indesign CC 2018.
I used this often before and so far there were no problems. But in my actual a book project he function is not working anymore. The error description says (roughly translated from German): "The selected text cannot be marked with tags, as it contains parts of hyperlinks or cross references. Please change the selected text so that it included only complete hyperlinks or cross references."

The file is not intensify complex. There are around 200 links, mostly links to pages (e.g. in the index) and links to URLs (http and mailto). So far there seems to be no mistakes. I didn't use any text anchors. And I load my own DTD list, nothing special there.
