I hope I’ll be of help.
Please let me know what you’re choosing for the menu, is it built using the header builder? or are you using one of the pre-built layouts in the Theme Options?
Kindly attach a file, with the theme options configuration and I’ll try to replicate it on my installation.
Go to Theme Options >> Backup and Restore
copy out the theme options settings under Export Options
add them to a txt file, and send it over
