There is another thread that touches on a similarity here:
That said, system updates are not the same as Software Store... but the Software store will check for all updates.
I looked over both screenshots and can assure you they are all safe.
The reason why you are seeing different versions is due to the presence of Snap and Flatpak in the Software Store.
Those package tools are seeking to update dependencies for themselves.
You can allow them, if you want. IF you are using Flatpak or Snap packages, they may be beneficial.
You can check with
flatpak list
snap list
You will see some Zorin Stuff listed that are Duplicates of the standard packages. That is normal, those are included in case the Zorin OS User is using Snap or Flatpak. So you should know right away if you see anything listed that you Know That You Chose to Install.
If you are not using either and do not intend to do so, you can do as I do and remove both altogether and solve the problem entirely.
sudo apt remove --purge snapd flatpak
