Opening Balances Change on Checking and Savings

I have had 3 occurrences where my Checking and Savings accounts were off. So fat it has been with Chase accounts. The opening balances suddenly change from $0.0 to $19.37 or $0.4 or $0.3.

I've also had issue with the transactions downloading completely. The update summary would say it downloaded 5 transactions, when I checked, there were none. When I did a manual download, 3 transactions appeared.

The first time it took me quite a while to find the trouble, now when it doesn't match, it's the first thing I check. Anyone else having a similar issue? Any ideas what is driving this?
