Hi,  
I’m testing Modular Rig in UE5.5 in the last few days and having this hard bug, I cannot rotate the Thigh FK control of the HindLeg module (for animal rigs), the lower FK controls works fine.

 ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/b/8/1b80d8c122233fe37ef3ed22ca00ff32d19ac93d.jpeg)  
Anyone can help me with this bug?  
Thank you,  
Truong
