Polycom VVX 400 - Unable to place any PARK keys on provisioning

Hello,

I'm setting up a bunch of Polycom VVX 400's and I can't get the provisioning template to place any BLF's for PARK on the phones.

If I manually add the Park buttons through the web interface of the phone, they do monitor 701, 702, 703 correctly...but only if I add them manually.

LINE KEY for SIP LOGIN provisions just fine. We are provisioning with FTP.

I looked through the config generated for the phone (mac.cfg) and it doesn't seem to have the correct entries. After adding the manual Park keys and exporting the config, I see that this is what it wants added:

attendant.resourceList.1.address="701"
attendant.resourceList.2.address="702"
attendant.resourceList.3.address="703"
attendant.resourceList.1.label="Park 1"
attendant.resourceList.2.label="Park 2"
attendant.resourceList.3.label="Park 3"
attendant.resourceList.1.type="normal"
attendant.resourceList.2.type="normal"
attendant.resourceList.3.type="normal"

How can I resolve this? I usually use Yealink phones, I've never had to drop Park monitors on a Polycom. I can't get ANY BLF to provision. Is there a different way to do this with Polycom?
