VVX 450 Intermittent loss of speed dial text on display

My VVX 450 keeps losing the text (contact names) from the display assigned to speed dial keys. It happens intermittently with no apparent cause, but they never last more than 72 hours before they disappear. I'm running Update on a Polycom Hosted Server, and he phone is provisioned for Zoom phones account.
