IPSEC XG to SG broke after XG V17 Upgrade

I applied the V17 update to my XG 16.05.x software appliance. Everything seems to have upgraded successfully except VPN policy and PSK.

Both Phase 1 DH and 2 PFS changed from Group 14 to Group 2. After fixing this, the VPN still did not connect.  I then re-applied the PSK on the XG from my notes and the IPSEC connected and is operating normally. 

I don't know if this is an N=1 situation, or wider spread but thought I would post about it in case someone experiences it.
