UE5 tilemap painting problem (new user here)

Greetings everyone, new UE5 user here and I’m transitioning my project (2D isometric tactical RPG) from Unity. I’ve encountered a bug when I’m working on paper2d tilemap and I would like to ask if there’s anyone here that can help me out?

In the 1st image, it’s a 32x32 orthogonal tile and nothing’s wrong with the painting. But when I change it to 32x16 isometric diamond tile, there’s always an offset from my mouse. It’s not a bug that hinders the process since I can just paint at any tile, but it’s quite annoying to always have the offset. Can anyone help?
