Photodropper will not search for key word, would appreciate any help available

I installed photodropper and was very excited about using it, but when I click on the hot air balloon and type a search word in, hitting enter to search does not work, it makes a ding sound as if there was something wroing. it will not search for a key word.

Also the drop down search parameters (i.e. anytime, last year, etc or relevance drop down) are miss aligned, they are up underneath the word search box.

I’d like to utilitze this plug in if anyone has any sugggestions to correct this issue.
