**CorOS Version:** 1.2
**Describe your issue:**
I reset the defaults on the 110 US PRN Brown FatJ10s cabs to a couple of IRs. After that, I’m unable to select the factory mics on the cab, so I’ve lost the “factory” cab as a result. The factory mics don’t show up at all in the picker anymore!
**Steps to reproduce your issue:**
1. Open cab
2. Select IRs and set them as new defaults
3. Try and find a factory mic
**I expected this to happen:**
If I reset the factory cabs to new defaults for IRs, I’m hoping to be able to use the factory mics/cab interface as expected if I desire.
**I have tried the following things:**
- Looking for factory mics
- resetting device/power cycling the device

Update since CorOS 1.0.3:
This was listed as fixed in the change log, however, I’m still experiencing the issue. Particular cab is the US 110. Thanks for looking into this!
