Proportional editing doesnt work properly on Make Human mesh

I wanna make some shape keys so when i am trying to use proportional editing i noticed that the faces on one side of this Make Human face behave differently then on the other when proportional editing done. For example on screenshot 2 you see that i selected two faces and by using proportional editing wanted to bring up the lip - but right side faces which surrounding selected face moving with it but on the left side - only one selected face is moving but faces surrounding it are just staying where they are. P.S. Face already has a make human rig applied to it (but i dont think that rig can affect somehowe Proportional editing.




I took the simple sphere then and did the same and faces on the sphere behaves the way it should be…but on the face its not.


Ooo. Stupid mistake. Solved! I had x mirror turned on on my model ))
