double box on page blocks

Strange issue using 7.3 (yet to upgrade)

Article View page - the article description block shows a 'double design box' when set to show title and box within page builder.

If I change it to just 'no box' then a single box shows...

However, on home page, and on article home page, the latest article block works as should do.

No box, shows content with no box, title no padding shows title and box (no padding) etc...

Trying this in another module (Modzzz business listings) and it works fine!... even on the view page, no problems.

Only seems to be affecting the one block at the moment on Articles View page - Description block

Any thoughts?

Yes, I would check the template; it could be adding in the designbox twice.

Look for this as well, if you are adding in code in the designbox code that also has the designbox, then it would get added twice.

Seems to only be the one box though, Article View - Desciption blox using Modzzz Ultimate Articles module.

May ask Modzzz if he can check. Doesnt seem to affect any other blocks in other modules...

No additional code added and nothing I can find in the template as get same using other templates!

PM me the site if you like and i'll take a look. 

Then that is where you concentrate your efforts to find the issue; the Untimate Articles mod.

 Strange thing it its only on my one site.

I have the module on another dev site but without the issue so not native to the module I guess...

Total idiot moment... it was in the html for that block somehow!

looked at all the possible reasons other than the most obvious...
