Size limits not being respected

Been using Sonarr since release, great software. unfortunately, recently i’ve noticed that it has not been respecting file size limits. i dont know if this has been an ongoing issue but i only just recently noticed.

I have the following setup for my limits:

yet yesterday’s episode of True Detective was downloaded in 3.5GB.

I did a manual search to see which releases were being rejected and there are many 4GB versions being accepted despite the limits being set to 2-2.5GB

and the one being rejected was for being over 4GB, though i dont even see that max file size in my limits anywhere. see image

what am i doing wrong?

Season premieres and finales are both allowed at 2x the size as they are often the two episodes that are double episodes but only labeled as being one.
