Single post inline ads displayed out of place

I am having an issue with the inline ads of the single post block. I am inserting an ad inside the Inline Ad 1 container and set it to display left aligned after the second paragraph. That one shows alright and right where I need it to.

Then I insert the appropriate code inside the inline ad 2 container, and set it to display left aligned after the 5th paragraph.

Lastly I insert the appropriate code inside the inline ad 3 container, and set it to display left aligned after the 8th paragraph.

And this is where the problem begins: The first ad is displayed – correctly – after the 2nd paragraph, but then the 2nd and 3rd ads are being prepended before the article, between the post featured image and the actual content of the article. It took me sometime to realize they were the 2nd and 3rd ads. I had to delete the entire single post template page and re-create it, just to make sure it wasn’t template-specific, but unfortunately it happened with the second single post template again. I’ve also tried all different paragraph order combinations, to no avail. Meaning I set the 2nd ad to display after the 3rd, 4th, 5th, 6th, 7th, 8th (you get the point) paragraphs, and similarly with the 3rd inline ad. None of it made any difference whatsoever. Every time I reload the page, the 1st inline ad shows after the 2nd paragraph I’ve ordered it, and the 2nd and 3rd inline ads, they are being injected before the post content (i.e. before the 1st post paragraph).

Please review the screenshots below which show the issue.

Please advise what it is that I have been doing wrong.
