Position glitch showing an image on hover

I’m trying to display an image under the text of my page when hovering over a row in this page: INDEX - Temp

As you can see, in the first 4 rows it makes it perfect, but from the fifth row the text begins to stay under the image.
It’s weird because all the rows have been copied and pasted and have the same configuration.

Could you help me? Thanks a lot.
