That is definitely not something caused by the plugin. For the same search phrase always the same piece of code is executed, and it will produce the same results.
Do you have any browser extensions active by any chance, which may affect the page layout? Something like adblockers or similar. In very rare cases broken extensions caused such issues.
You should also try a different browser, just in case there is something wrong with that.
I tried to test, but I can’t see the plugin on the page anymore. Can you please let me know where I can replicate this issue? I am more than happy to help, but I need to know how to reproduce the problem to be able to help.
