One this page I set the children to the correct sex and created them but they were returned to unknown sex when the record got created this is a pain!
I just visited the profiles of the 2 children and edited the "unknown" to male/female without issue. Perhaps there was a momentary glitch.
Yes, this was a problem with the source linker on September 19 and 20 but has been fixed. Any children that were created with unknown sex during that time will need to be manually edited to set the correct sex.
Thanks Alan and Aine!!
