Multiple Contact Dates

[QuezXLV]

Not sure if this is specifically related to anniversary dates or just multiple dates within a contact, but the second date is just formatted as numbers in Etesync. Also, not positive if related to Etesync, but when I synced my contacts, those second anniversary dates in the contacts on my phone (not in Etesync) are all incorrect and all seem to show a year of 1610. I wonder if these two issues are somehow connected.

Can confirm, I'm getting the same issue
