Reheat loop not connecting to the terminal units- OpenStudio

Can anyone help with troubleshooting a hot water reheat loop that does not seem to be connecting to the terminal units in OpenStudio 1.9? I have the connections checked for each terminal unit coil but the unmet heating hours are >2000. If I remove the reheat completely the unmet hours are about the same. So that leads me to believe the connection isn't happening. I've gone to letting the boilers, pumps, terminal units, coils, everything autosize. So capacity should not be the issue. I followed all the recommendations on from AParker's post on 7/21/15 (https://unmethours.com/question/359/what-are-your-techniques-for-reducing-unmet-hours/) which was very helpful- thank you. Any other thoughts?
