Missing companies in API this week

There are a bunch of missing companies in the sequence this week - either because they are not in the API or because they were stillborn - assigned a number but not in the register. The numbers missing are:

For England and Wales: 11501836 - 11501889, except 11501854 and 11501873 (52 companies)
For Scotland: SC604465-SC604470 (6 companies)

Please advise whether this is a data error, or the companies don’t exist, and the numbers will never be assigned?

I can confirm that these companies do not exist and the numbers will NOT be assigned.
