GetAppCredentials from Framework has validation issues

Hi Everyone,

After upgrading from UiPath Studio 2016.2 to 2018.1.4, the GetAppCredentials has validation issues as shown in the picture:

If I uninstall one of the packages (UiPath.Framework.Activities 1.0.5905.30080, UiPath.Core.Activities 18.1.6680.15559), close UiPath Studio and reopen it, the issue is gone, but at a later run is appearing again.

I have several bots scheduled daily in Orchestrator which are failing due to this, they run perfectly at the next day run if I do the steps above, but they fail at the next run.
Any idea why?
