2 Versions of Photoshop

Hello,

I have 2 versions of Photoshop, namely 21.2.4 and 22.1. 

I think the cause of this is because I didn't update my photoshop when the 21.2.4 version became available. When I opened my photoshop after not using it for sometime, I noticed 2 updates available. Thinking that the 22.1 version is the latest, I decided to update the 21.2.4 version first but encountered an error message that there is a conflicting error. I proceeded to update to the 22.1 version which went through successfully. 

But the update to 21.2.4 version remained in my notification. I click on it to see if it works and the update went through this time despite my trying to cancel it. 

Now I have 2 versions of photoshop. I would like to seek the advice of the community as to what I should do now. 

Your assistance in this matter is much appreciated.

Thanks & regards,

Gillian
