Bought Realm Plus but cannot access free packs

A month ago I tried the free trial of Realm Plus in my bedrock account, yesterday the trial ended and the payment was done automatically, so I remembered that one of the benefits were "access to +150 resource packs in marketplace..." and wanted to try some of them in my world (Realm) but noticed that there were just 15 available and when I clicked on "more packs" it appears like I have to buy them..? why? Also when I go to settings – suscriptions, I noticed that the option to buy Realm Plus is there, like if I hadn't buy it yet, and i'm afraid to click it (what if I do and then I get another payment?) 

Btw, I got the Google Play Store and Paypal notif. The money do was taken fom me.

 

Hope you can help me, thanks.
