Cant get rid of 'Form Elements'

Using the Builder, I started with the 'full' set, and the added and removed some items.

After uploading to my server, i saw i wanted to make some changes - and i removed the 'Form Elements' module.

i uploaded the "plugins" folder and the "build-config.js" to the server again.

but despite having refresh the cached - i still see the Forms toolbar in the editor.

I tried in a different browser too (that i hadnt used before) - and it's there too. although clicking on the form toolbar buttons - does nothing. How can i get rid of the toolbar?

thanks!
