I'm not seeing what you are seeing. What I am seeing is that both cousins are in the report. The children appear under the first one with numbers appropriately assigned. Then, the kids are duplicated under the second spouse, but with the same number that was used for them under the first spouse.
From that point, only the child's descendants are shown. The Line of Descent only shows the first parent's line and not the second - and there is no indication there is another ancestor up above unless you happen to follow the number and see it appears twice in the register report.
Look again. I'm pretty sure you will find the numbers are NOT skipped. They only appear that way because the second cousin to appear uses the first cousin's kids' numbers.
[Edit from original post: the report skips printing the second set of numbers the descendants would otherwise have and print the numbers assigned under the first parent. This is because subseqent generations will have numbers coming from the first parent.]
This same behavior happens to all of the register reports.
In olden days, before computers, this part of a published genealogy in a book would simply say "see husband's number xx for the descendants of this couple"
