Auto split- Learn regions from text file bug?

When trying to use the Auto split - Learn regions from text file function, XML style text format works fine. However the other two options (tag=value, tag tabulation value) don’t seem to do anything.

Both of them work fine in W8.5
Did something change in W9? Do I need to format the text in a different way or it is a bug?

You are right. I will fix that for 9.0.30.
In the mean time, please use XML.

I have now the version 9.5.50
How should the textfile or xml file look like.
Dokumentation in Wavelab is strange and not understandable.
