Help Font size trouble

Okay, so, I was modifying my sig today, and whenever I tried to use the font "System", it wouldn't allow me to make the font size smaller. It just stays the same.

is this just me, or is this a problem for everyone?​

 

Works fine for me. You could try doing the BBCode manually.

 

I tried :\ Still won't work D:​

 

I haven't checked the signature edits yet, but when I try to modify my size of the text and try to add spoiler tags, it barely let me... I guess it must be fixed now though eh?

 

It's only that one font for me. It won't go smaller at all. I haven't tried making it bigger, but I don't really care about bigger. I want it smaller :c​
