Chaining sequences and got a bad camera between

I try to play 2 sequence in a row, the second one is conditioned by a variable.
PlaySeq1 → if bool PlaySeq2 else PlaySeq3

My problem is, between each sequences, I have a parasite frame.

In my sequences, I put directly the skeleton mesh, with animation, so the sequence spawn the mesh and remove it after.

It’s difficult to know if it’s a frame back to my gameplay cam (with cut) or a camera without my characters.

Did someone have similar issues ?
