Question about Adsense format…

Hello

I have a question about how the ads are showing up on my sidebar on the right hand side.

Now, I am not sure if I am hallucinating (hopefully not)
https://calicutstudents.in/

If you look at the ads you will see that they are showing up in 3 lines
1st line has heading(its underlined) and the url followed by the heading

2nd and 3rd line has the description

Now If I recollect properly the ads were showing up in 3 lines before.
1. heading
2. url
3. description
4. description continued…

similar to the ads showing up at (kindly refresh the page a couple of times if you see an image ad and hopefully the text ad will show up)

https://calicutstudents.in/general-topics/calicut-university-distance-education/

While it is not an issue that the ads on the main page are showing up in 3 lines instead of 4 BUT I think that the empty space between each ad does not look very good..

Now here are the changes I have done in the past few days

1. Upgraded to the latest wordpress version …3.1.4

2. I had played around with the sidebar from within wordpress where I had added categories and something else…but I removed everything and this should now be back to what it was before (default)

3. I had used Search&replace and replaced all the
<hrefs
in my post with
<!–adsensestart–><href

this was to help with the adsense plugin I am using in my site…

but this should not have changed anything for the ads on the main page is what I understand.

Other thank this I am not sure what is changes or wrong here…

can an additionally big category change this ?
Or can I simply change the box within which the ad is ? (if that is the case if someone could point me to that then it would be great)

Thanks in Advance for your help !!

Regards,
