This is a known issue and there are a few options to try and fix it. But none of them are perfect.

The easy but much less perfect option:
enable bump protection in the config. Under Protections, the first option is bump. Enabling this will fix the issue but it also has its downsides, mainly that players won't be able to walk while AFK and will need to jump or interact with the world in some other way to be able to leave AFK.

The less compatible but much better option:
you can install AFKPlusPrefix and leave ShouldCollide set to false. This will stop AFK players from being bumped by non-AFK players.

For mobs there is one simple fix, there is a protection called MobTargeting. Enable this and hostile mobs won't target AFK players and therefore won't bump them out of AFK.
