Sidebar & Top of Page Showing Numbers When Dependency Enabled

Hello,
I am building a product builder, and I want fans to show up depending on the case selected (and whether or not that case includes fans). I have made an attribute for Yes if the case includes fans, No if otherwise. However, now the page for Fans shows random numbers at the top and side. Any ideas on how to fix this?
Thanks!

(Also, on an unrelated note, is this plugin safe to update to Woocommerce 4.0?)
