how can I prevent all the characters from overlapping?

Hello, I attributed the behavior patchfinder to the enemies, the behavior works well but the concern when it gets closer to me, they overlap, I thought about assigning them the solid behavior but the problem I also assign to the enemies line of sight and give as a condition if the enemy does not see me it turns between them, to make clear, I can not assign them the solid behavior otherwise they are blind, they do not move. I don't know what I can do to replace the solid behaviour so that they stop overlapping. I thank you in advance for your help.

In the "Pathfinding" behavior under the Enemies Family, you can change "Solid" to "Custom" in the dropdown menu

Then, just make an event at the start of the layout that does Enemy Family > Pathfinding > Add Obstacle (Enemies)

thank you but I also attributed to the enemies line of sight, I did as you told me, I did the same with line of sight, but the enemies remain blind when I attribute them solid

I found another way to do it and it works, I attributed the solid behavior to the enemy and 8 directions control by default disable, so enemies move well and follow me
