M2 upgrade/update not showing es expected

Hi. did the purchase for the upgrade of Membership 2 Pro, but after doing the purchase, it's still asking me to upgrade in order to update.
When going to the plug in and selecting update, it will direct me to the plug in's page, and give the option to install. But after clicking on install, it takes me to the page showing all the plug ins from WPMUDEV, and nothing is updated. What could I be doing wrong?
Thanks for your help.
