IDT Universe on ECC Infosets - Error

Hi All

I am trying to create an universe on IDT BO 4.0 SP 4 directly from ECC Infosets. I can see that the some of the infosets have repeated field names in them. As such I am not able to proceed further and mapping of multiple infosets results in longer query run time in preview and in web-i.

Is there any solution to move forward or is there any ways to edit the repeating field names in the infosets ?

Kindly help 🤯
