Regarding the vertex problem of level

I have some questions about the bevel I generated. Can someone help me answer

Hi and welcome, What are your questions?

It’s difficult to tell just from the image…
If you could share a blend file with just the magazine part, it would be better.

But you could try to check if there’s any duplicated vertices, or any non-manifold geometry around that vertex.

Welcome :tada:

I could replicate this when:

  • not every edge is selected
  • scale is not applied

like so (try the slider):
