Heading style easy and quick fix ?

Misleiloee 

I am unsure what is going on.

What I am seeing is:

1. You have direct formatting on each of these to turn off Bold.
2. When I import the Heading 1 - Heading 9 styles [three times] the Heading 2 style in the target does not apparently change.
3. If I use Replace to Replace Heading 2 with Heading 2 the numbering and spacing do appear. The text remains having the Bold turned off.
4. If I first go to the Heading 2 style and manually turn off the Bold (that makes it not bold) then when I do the Replace, the styles are identical.
5. I can also first select all text in Heading 2, click on the B for bold on the Ribbon tab, and then do the Replace and the styles are identical.

I hope this helps.
