Incorrect clownosity detection with polka-dot bow tie

The polka-dot bow tie gives 3 clownosity, but when I was wearing it and the bloody clown shorts the guide still said I needed one more.

I confirmed that this isn't an issue with item description, as I can indeed open the door wearing just those items; I am currently fighting The Clownlord Beelzebozo and the guide is still saying I need one more clownosity.
