unknown birthdays on calender?

[jovial dirge]

I´m currently on my first year, 25th spring. Only now did I see that there was an unknown birthday entered in the calendar on the 8th and the 23th.
Both of them has a "?" and the picture is the one from the mayor^^°
Would anyone explain that to me? is it a placeholder for the merfolk?

Thank you very much for your help.

It's a bit of a bug, but it's assumed that they will be for the merfolk, yes. Connor does not, in fact, have multiple birthdays. The devs have been made aware
