Sterling Majesty whammy bar hole problem

Hi everyone, I’m having a problem with the tremolo bridge, specifically the hole where I’m going to insert my bar. The bar fits perfectly, but the hole is raised (where the fixing screw is) and seems to “move” together with the bar. If I have to pull the bar forward or backward, this raised part of the hole moves with the bar when it should actually stay still and this annoys me while playing. At first he didn’t. How can I resolve this without making a mess?
