Doser Maxi Slave Speed Grayed Out

I have a Profilux 4 and a doser maxi slave that I've been using for several months without issue. I'm switching over from saltwater to freshwater so I did a factory reset on the Profilux and also updated to the latest firmware. Now the doser maxi speed control is grayed out in the GHL Control Center. It's set for slow and I can't change it. That doesn't work too well considering that I use the doser for AWC and I need to move large amounts of water several times a day. Am I missing a setting that's causing this?

Thanks!

When you say "latest firmware", what firmware version are you referring to?
Did you assign the Maxi to the ProfiLux? PAB device assignment.
