Hello,
a new feature of template inputs was merged in core to develop branch. Since it was based on REX inputs, a lot of code from REX was brought to core. That means we need to update REX and remove the code from there. This is currently WIP [1]. If you have REX plugin in your setup, when you start a Foreman, you’ll see an error with duplicated number of migrations, until this is done.
In a meantime, you can either disable the plugin or help testing the PR [1] which should fix it. At least Foreman will start with it applies.
