(Spoiler) Question about Hazmat suits

Hey all, I have two sims in my household that I am using to play the mystery. I am trying to assemble two hazmat suits. My sim has the spore filter in his inventory but everytime I talk to the Curio shop owner he keeps saying "You already have an incomplete hazmat suit in your inventory" (or something)... when this sim does not have one. The other sim already assembled her hazmat suit with the spore filter. I can't complete his aspiration goal of assembling a suit without this.

Is anyone else having this issue? Also, I tried moving him out and into a separate household by himself and I still get the same pop-up message from the shop owner.
