Problems with generating target files in MIF 10 format

Question

For a translation of FrameMaker 10 files from German into Chinese we used the exchange format MIF 10 for Trados Studio. But for 8 of 19 files we cannot generate target files. Studio gave the following error message: 'The index laid outside the area. It cannot be negative or smaller than the list. Parameter name: index' (this is a translation of the German error message). 
 As workaround I've used the MIF 11 format, translated the files with the TM, but the error message still appears and no target files are generated. Does anybody know how we can get target files?

Dear Jerzy Czopik 
 These files work perfectly for me in 2021. But they are a problem in 2019.

 We can try two things... you choose: 
 
 You can send me your translated SDLXLIFF files for these files and I'll try to get the target out for you, or 
 I can add you to the Beta for 2021 and you can try it yourself? 
 
 Drop me an email with the way you'd prefer to go?
