Seeing old version of an asset I've updated in version 2020.3.4f1 LTS

Hi I’m using unity version 2020.3.4f1 LTS. I’ve recently downloaded and updated the latest version of a unity asset called RPG builder from v 1.0.4.1 to version 1.1

However, every time I go to update the asset, it automatically reverts back in my package manager back to v 1.0.4.1.

I have tried opening different unity projects using version 2020.3.4f1 LTS and the same issue occurs, however, I just tried a random unity project that was version 2019.4, and when I viewed the same asset RPG builder in my package manager I have the option to download version 1.1 which is the latest version.

So my question is how come I can see the updated version available in an older/different version of unity, why do I keep having the option to update and keep seeing the same older version in version 2020.3.4f1 LTS and how do I fix it?

Bump can someone please help me with this issue?
