Hello,
Don't know why I did not see your reply. I am checking all un-rep tickets.
About your problem, if I am understanding correctly you mean, I think that you are selecting products from Tabs, not from Products so you don't have much more settings.
I mean you should select the Modify with Products like this: https://prnt.sc/88SptW9PLaNn then you can choose the correct target for products, it will show properly as you want.
Now you select Tabs: https://prnt.sc/3U0QrFSP380s
I keep a block that I create on your site to be an example. You can check if it is you mean.
Otherwise, please contact me via skype: vetyame
I will support directly for your issue to be solved quickly. Thank you so much!!
