Yes, I'm aware of that and I've decided against automagically resolving this. because this would be a breaking change for users that rely on the original semantics of this field.

A way to workaround this is to create a field mapping in Mp3tag at Options \> Tags \> Mapping. To use GROUPING as the name for the iTunes grouping field in both ID3v2 and MP4, you'd create a new mapping

Tag: **MP4**  
Source: **CONTENTGROUP**  
Target: **GROUPING**

To use WORK as the name for the iTunes work name in both ID3v2 and MP4, you'd create a new mapping

Tag: **ID3v2**  
Source: **CONTENTGROUP**  
Target: **WORK**

Let me know whether this works for you.

Kind regards  
– Florian
