Hello @blade,
Thank you for reaching out to us and bringing this to our attention.
I'm not sure if I understood correctly the issue.
Could you please elaborate a bit more about it?
So far I understand that it is working as expected, right? I mean, when the "Enbl" checkbox in the Multi-pass window is enabled, then the "Multi-Pass Image" options for saving those files becomes available in the render settings, correct?
If you disable the "Enbl" checkbox, then those extra options became unavailable, correct?
Are you using the Multi-pass feature at all?
If not, you shouldn't have any issues.
Looking forward to hearing from you soon.
Have an amazing day/evening.
