Custom Field Template: Back End..broken breaks if too many checkboxes

Hello Mr. Author..

I have noticed that if I use two three keys with value labels..to be diplayed as checkbox…then the display breaks with..with the ‘key label’ appearing further below than the values..and the next ‘key label’ and values moving further down with large empty space ..

this of course is in the backend..(add new post in custom field template..)

This error is encountered only if two three checkbox keys are used (also the number of check box options are large..(50-60) in each key..key examples are..’state,location,school..etc..and each key has multiple check box options..(i hope I make sense)

If the type=checkbox are fed in between keys with ‘text area’ or ‘select’options..then the display is fine..any idea why this happens..
