Cross filter direction issue!

Hi everyone!

I have a data model consists of many table but I needed a bidirectional relationship between 2 tables. Now 1 table already has 1 bi-directional relationship with the another table(s) and while changing the direction from single to both in those 2 tables i need, it gives me following error. Can somebody help me to understand what's happening here? Why am I getting it and what could be done to fix this and have this as Both? Changing the other connection to the other table from both to sing makes this work but can't do that since that breaks many visuals/measures.

Thanks 🙂
