Foundation adding strange things

I’ve asked about this before but didn’t get a good answer and now I see where the problem is, but don’t know how to fix it.

I set a size on a spacer of 15px (as an example), and when I saw it was too high, I set it to 10px, but nothing happened. I exited out of the program, turned on and off foundation watch and it still wouldn’t adjust the size. When I used the inspector tools, I saw that foundation was spitting out the size “15pxpx”. I’ve included a screenshot to show you. Can you fix this habit?

Can you show us the code that you are using to apply that spacer?

I actually figured out the answer to that one. I was putting size=“10px” instead of just size=“10”.
