Hi!
1. There was a custom CSS applied on the search bar for max-width:1100px and it caused the issue. I have added another custom CSS for the results as well:
[php].wpdreams_asp_sc {
max-width: 1110px;
}[/php]
It should be working fine now.
2. Because the keyword suggestions source had an unset taxonomy selected. I removed that from the keyword suggestions list, now it works 🙂
