Text Dialog action missing on Android 6

I tried to import a project to an old phone and it failed. After a bit of investigation I found that the List Dialog and Text Dialog are not shown in the Input action group. That is, unlike other settings, they don't show red with a message telling you what version of android is needed. Also, I don't think they should be missing, as the dialog used by Text Dialog is available on Android 6.

This is with the latest version of Tasker.
