Inappropriate warning for half-siblings with same father [closed]

I get this upon save:
Warning: Check the data.
  1. A birth date (Halvorsen-878 born 23 Jul 1814) should not be within eight months of a sibling's birth date (Halvorsen-740 born 2 Sep 1814) unless they are twins born within a day of each other.
These two boys have the same father, but different mothers. Although children of the same mother must be born at least nine months apart, I can't see any physical reason why children of the same father can't be born within nine months of each other.
Halvor was quite the womanizer and fathered three children out of wedlock, in addition to five with his wife.
