Content Manager showing Rexaccuseason_ade not installed Why?

I purchased and loaded Rexaccuseason from ORBX. It seems to be running file, however, when I look at msfs 2020 content manager it says Rexaccuseason_ade not installed.

Is there a reason for this? What do I need to do?

I also show a similar one for BKSDuke_temp which I also have loaded and seems to run fine.
Any one know why that is?

Thanks for the help… Bill
