Inconsistent Timeline entries for married couple's children birth events

Hello,

I have noticed something strange. There is a family that has both a Mother, Father, and a Son. The son’s birth event shows up in the Mother’s timeline, but not he Father’s. Both parents were alive for the birth event.

I’ve checked other families and this issue is not appearing consistently, and nothing is sticking out as different between families where a child’s birth event shows up in both parents’ timelines vs families where it may be missing in one parent’s timeline.

I am running gramps web on Debian 12.
Gramps 5.2.4
Gramps Web API 2.8.2
Gramps Web Frontend 25.3.0

Can you check if the child ref has child reference type “birth” to the father?
