I think with the last update of the software something related to ignored transactions got broken.
I have some transaction related to IOTA in my history. Some of those transactions are marked as “ignore”.
Until some days ago those transaction where really ignored and the total number of IOTAs was correctly show on the portfolio overview.
But now it seems like these transactions are not ignored anymore, although they are still marked and shown as ignored. The number of IOTAs on the overview includes now the amount of the ignored transactions and is therefore too high.
