Filtering broken on product list pages

The filters on the 3D Printers list page is seriously broken. With no filters it shows 50 products, with just Type set to FDM it only shows 10 products, the Intemsys, Modix, and the CR-M4. Without Type set, selecting Creality for Brand results in 6 printers listed, five resin printers and the CR-M4.
I hope that pointing this out is helpful.

Wow, that’s definitely strange behavior! It sounds like the filters might be working counter-intuitively. Thanks for pointing this out, it’s super helpful to have users like you catching these things.

Have you tried contacting the website admins about the issue? They might not be aware of it and would probably appreciate you letting them know. In the meantime, hopefully someone else with more experience can chime in with a workaround.

We will report this to our web developer and work on a fix. Thank you, Chris
