A few issues with my plugin

Hi,
I have purchased the plugin today and I’m having a few issues I’m not abling to resolve.

1. after adding to the cart I don’t want them to be able to add again to the cart
2. how can i activate frequently bought together on cart and checkout page?
3. Variation on the product page looks strange like in this screenshot: https://prnt.sc/bFDflfkhtBoU
4. for some reason on the product pages that i didn’t set any bundle, it shows lots of products like in this screenshot: https://prnt.sc/xp-Df3Yl9J6X
5. I cant choose 2 variations, not in none of the products offered via the plugin (I can’t choose only one) like in these screenshots: https://prnt.sc/648TFrmOEwPf
6. It ain’t letting me add only the first product until ill fill in the attributes of the second product even though i don’t want to add: this product https://prnt.sc/hM70Qr-wKaSy.

Feel free to enable and disable plugins if you need them.
Im using Astra theme pro.
