columns not behaving when clicking on dif m-item

the parent item for both "transmode in brief" and "contact us" is an alias to "transmode in brief", About Transmode. There is no column set here

this is not a problem, you can give it a submenu width in the params, so you fix it to 360px

That has fixed it.

The problem was that it wasn't doing that before without setting the sub-menu width. Suddenly it became a problem. I can look at both solutions and neither had the sub-menu width set but one worked and the other didn't so I couldn't find the problem.

Thank you.
