After rigging - each joint has 2 dots o_o

[Legosky007]

So i downloaded model from assetstore. Rigged it in Cascadeur - it was totally fine except for bad retopology. I uploaded model to Blender, fixed retopology. Did not touched bones.
Uploaded model to the Cascadeur again - did the autorig thig. And this time each joint has 2 dots. What? How do i fox that?
