I have a strange issue with a chart that I've not seen in the past. The chart shows my portfolio value over the last 12 months on a weekly interval. For the week ended 12/25/21 there is a strange spike in the chart. When I click that bar the account balances for that week appear double what they should be. As you can see from the picture this isn't happening for the other weeks.
When I turn off "Include unrealized gains" the spike goes away but I want that option on so I can see relatively up-to-date balances/performance.
Any ideas what could be causing this?
FYI, there was no other significant activity going on in those accounts during that week. No transfers in or out. Just a few transactions of buying and selling of securities.
