Ownership of Digital Content Before Game Pass Ultimate

Hello,

I just wanted to ask a quick question regarding something I have seen on the xbox store. Within the past couple months, I decided to upgrade my gold subscription to a game pass ultimate subscription because 3 months for 1 dollar was a pretty good deal. Before
I made the switch, I had bought all three major Destiny 2 expansions, being Forsaken, Shadowkeep, and Beyond Light. Additionally, prior to getting game pass ultimate, it did show that I owned all three things on the xbox store. After getting game pass, I got
a little curious and now, when I go to the pages for the respective dlcs, it doesn't show that I own them but rather gives me an option to purchase them (I think it impacted these three expansions because all three are on game pass).

This being the case, I just wanted to ask if this is supposed to happen as a sort of visual glitch thing or if my ownership/licenses associated with the expansions were wiped out when I upgraded. I am still able to play them at the moment and nothing is
wrong, I just want to know if I don't renew my game pass ultimate and go back to gold, if I will still own them because I bought all three expansions before getting game pass ultimate.

Thanks in Advance!

:)
