Hey again, no worries.
If you check your System Settings > Apple Account, (Formally referred to as Apple ID), you’ll probably see two different accounts, one in iCloud and the other in Media/Purchases.
If you don’t, then you may be signed in with this other account separately in any number of apps, whether it be App Store or the TV app.
It may confuse things less if you were to sign in and stick with one account for both, although those purchases cannot be transferred to another Apple account, so that might make you not want to separate them. Some people prefer to keep separate accounts, while others may mistakenly have two accounts in use for different services.
In any case they are two different Apple accounts, as long as you don’t lose access to either should be just fine.
