My Entity Spawn's only in dungeons in Mcreator Eap 2021.3.b49312

Hello! I have already reported a bug with my mob. Thank you for fixing it, but during the check I noticed a strange thing (Perhaps this is a new error)
I found my mob almost always in abandoned mines. Perhaps this is a new bug and the mob appears only there. Here are screenshots of my settings again, and screenshots where I found my mob. 
If this is not a bug, then let me know what is the reason for such a change in spawning (On version 1.16.5 everything worked fine and the mob was both in caves and in structures)
