Issues with Oceanic VT3 "HI NI Go UP"

[DiveRef]

My wife has a Oceanic VT3 Dive Computer, We have had it for about 5 years, We have done it this year for 2 weekends the first we had no issues, she has never hooked it up to a computer to download dives, so when we got home we synced it, got her dives off of it and it had an update so we did that. We took it out again last weekend to dive, and as soon as we got down at depth her alarms started going off, displaying "HI NI Go UP" mind you this was not even 2 mins into our first dive of the day, no drastic elevation changes, same spot we dove a month before the update and had no issues. Has anyone had this issue before how did you resolve it?

Thank you
