PSE version not consistent

I am preparing to move my catalog to an EHD. When I check the system info it shows as Vesion 18. I have never had PSE 18. I have PSE 2020. do I need to reinstall the program to be using the 2020 version? Or did they just do some tweaks to 2018 and it is 2020 that I am using?
