Ubuntu 22.04.4
Evolution version: 3.44.4

I have been using Evolution for a long time. Now I am on a new laptop with above versions.
Evolution shows some very strange behaviour. All memos are shown on 2 successive days. For example, if I enter a memo on a Monday the memo is shown on Monday AND Tuesday. This is very annoying behaviour since there are now double as many memos in this Evolution installation.
Would be very grateful for help. Any ideas?
