Used Iris+Fabric for install, but it says theres no Fabric installed.

I just installed Iris, and I intend to use it with a couple other fabric mods, so I hit the Iris+Fabric button. When I try to load the game though, it says a couple of the mods (Double Doors and Collective) need fabric and that it is not installed.

Here is the errror code:

Incompatible mods found!
net.fabricmc.loader.impl.FormattedException: Some of your mods are incompatible with the game or each other!
A potential solution has been determined, this may resolve your problem:
  • Install fabric, any version.
    More details:
  • Mod 'Collective' (collective) 7.61 requires any version of fabric, which is missing!
  • Mod 'Double Doors' (doubledoors) 5.8 requires any version of fabric, which is missing!

My understanding is that I installed Fabric with the Iris+Fabric button, but I guess thats not entirely the case. I've tried reinstalling a couple times, and it has not helped. Any help?
