I hope this will help, but I'm not sure. Numbering is a combination of formatting for paragraphs. By numbering so many alternating paragraphs, I suspect there is confusion and the numbering style or List Paragraph style that is in use is being edited when you mean to only edit selected text.

If you need space between numbered paragraphs, I would use paragraph spacing or you can insert line breaks instead of paragraph breaks. (to insert a line break, hold down Shift and press Enter). Try doing one of those instead of having those empty paragraphs.

It is possible to have numbered paragraphs and then some non-numbered, and then return to numbered, but to have every other paragraph numbered seems like it would be troublesome. I hope this helps.
