XML Exporting Bugs with Audio Lines duplicating

When exporting a sequence in xml Premiere Pro and importing it into Davinci and vice versa the Audio lines are extremely bugged. 

For example 
1, 2, 3 (Mono)
is duplicated into mono clips by Davinci and Premiere Pro too and thus should turn into 
1L, 1R, 2L, 2R, 3L, 3R (Stereo)
but instead turns into
1, 1, 1, 1, 1, 1 

I have tried to fix it using Premiere Pro and Davinci resolve on different PCs.
In addition to that Ive tried all possible export methods and validated the xml file on the internet but nonetheless some versions could not be imported into Davinci Resolve, no matter if I exluded clips, removed all attributes, turned stereo into Mono and vice verca, used a clip without any edits. Sometimes when importing there was an error: "DOM parser error . Line ..." even if it was only a single clip.
Apart from that the FCP Translation Results said: "Translation issue:
Effect <MPEG Source Settings> on Clip <"Name"> not translated." Removing that clip did not help though.

How do I succesfully export a sequence from Premiere Pro into Davinci Resolve and vice versa?
