Chute / retention issues

Recurring problems with retention. Medium roast coffee. 1-2 shots per day. I clean with grindz periodically. I have to go in with a small paintbrush almost every other day. I can feel it hit the plastic piece and that’s when grinds trapped behind it fall. I’m using fresh beans from individual packs in freezer - I don’t RDT but there is some condensation from that.

Thoughts? It’s super irritating to need to do this all the time with this grinder. Otherwise happy but this interferes with dialing in.
