when entering numbering it enters bold and normal numbers randomly - why?

in writer numbers are randomly entered as bold and normal.

Edit your question to describe the context: what is this “numbering”? Chapter numbering? List item numbering? Just plain ordinary numbers in the middle of the text?

Are you adding the numbers after having typed the text or simultaneously to typing? Are they typed with the numeric keypad or main keyboard?

What is your intent? (What are the numbers for?)

Don’t forget your OS name and LO version.

What are those numbers?

Content typed in as running text?
I see 3 french hens, 2 turtle doves and 1 partridge.

A numbered list?

  1. partridge
  2. turtle doves
  3. french hens

Table entries?

Numbering for headings?

Something else?
