Weird bolding and changing ordered lists

I can help you with some questions not all.

1. Try a different practice. Enbolden the whole content and then unbolden them. This would remove boldness from all letters.

2. -

3.  You will have to change the numbering on every sentence of the ordered list manually.

4. Adobe is not good at changing the PDF document to Word properly. So what I do is I use the free online services available to convert a PDF file to word.

Honestly, editing a PDF in Acrobat is rather unpredictable, to put it gently. Acrobat is great at a lot of things, but precise formatting is not one of those things. I reccomend you recreate the documents from scratch in a proper program, such as Word or InDesign, that will give you control over the formatting.

But if you must just continue using Acrobat to edit the PDF, here are some things to try.

1. When getting weird bolding issues, try pasting the text first into a plain text editor. Sometimes, I even paste into the subject line of an email (as it strips out the formatting). Then I copy and paste again into whatever program I needed the text for in the first place.
2. Hanging indent: Make a separate text box for the numbered list. To indent an entire paragraph, use the Edit tool to resize the text box. It's worth noting that Acrobat doesn't treat text editing like a word processing program, where you can set precise measurements for things like indents, margins, tabs, etc., and expect to be able to use them document-wide. Think of editing in Acrobat more like each individual text box is a separate piece piece of paper, cut out and pasted onto the page. Each text box has absolutely nothing to do with the other text boxes.
3. To change a bullet or number in an ordered list: sometimes, Acrobat treats the bullet or number as a separate text box. You'll be able to edit the text in the hanging indent, but it won't move with the main body of the text. Again, this is another reason to create the document from scratch in Word or InDesign because Acrobat will never behave the way you want or expect when trying to edit ordered lists.
4. The boxes you're experiencing aren't form the document getting created in Word. That's just the way Acrobat handles text editing. It does it's best shot at figuring out which boxes go together.

My final words of advice are to think of text editing in Acrobat like using white-out on a printed copy. If the change in your text is small enough that it can be done with white-out, then its appropriate to do that change in Acrobat. If the changes will require half the document to be whited-out, then Acrobat is not the place to make those changes. Go back to the original source document. If you don't have the original document, recreate it, or at least recreate just those pages (in your word processing tool of choice) and then replace those pages in the PDF.ac
