error while importing model in substance painter

hello guys.

when I import my model in substance, it shows me an error like this;

[Scene 3D] Errors have been found while splitting meshes per UV tile:
Mesh 'mask pCylinder1' has a face spanning across multiple tiles: UV tile 3, 0 (UDIM 1004) with vertex at U=3, V=0.316657
Mesh 'mask polySurface15' has a face spanning across multiple tiles: UV tile 4, 0 (UDIM 1005) with vertex at U=4, V=0.550256

I double-checked everything and I changed every Udim.

Please anybody has an idea??
