I am successfull to reproduce your trouble
I didn’t understand that you downloaded the package through your favorite provider: www.modxcms.com
What I have done:
1/ remove my own gmaps from my installation (a remove package, not an uninstallation).
2/ I downloaded the package from www.modxcms.com => Gmaps is available for installation
and then I get the message - Update available - Please select gmaps101_331.zip
If you download manually the package from the repository and you move the transport.zip file it in your package folder you haven’t this trouble.
So, I think it is more a trouble on the provider side than a wrong packaging itself. It’s not normal to have a zip file (not a transport.zip) available for upgrading.
To solve this point:
- remove the gmaps package (force the removal)
- download the revo gmaps.transport.zip in your package folder.
- search for a package from locally (the third choice)
- install the gmaps package.
Gmaps should be installed with No updates available.
