Upgraded Rasa and FormPolicy is not working

After upgrading Rasa, I replaced my current config file to the default one generated by ‘rasa init’, I also added the FormPolicy into the config, as I have several form actions in my bot, however I keep on getting this error message when I I try to train the bot: You have defined a form action, but haven’t added the FormPolicy to your policy ensemble. Either remove all forms from your domain or exclude the FormPolicy from your policy configuration.

It doesn’t matter if I remove the FormPolicy or not, training the bot will result in the same error message. I also copied the policies from Rasa’s formbot example, nothing worked!

Please help!!!
