Error after updating JUX MegaMenu

Hi,
After updating JUX Mega Menu 3.2.3 to 3.3.0, I've got the following errors above the menu :

• Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in /XXX/storeseas/modules/mod_jux_megamenu/helper.php on line 152
• Notice: Undefined offset: 0 in /XXX/storeseas/modules/mod_jux_megamenu/helper.php on line 222
• Warning: Invalid argument supplied for foreach() in /XXX/storeseas/modules/mod_jux_megamenu/helper.php on line 222

(Actually, the first warning is on the website on my computer, not on the staging website)
Could you explain me (and not do by yourself because I will have to reproduce on production website) how to do solve this issue ?
Best regards

Hi HaiND,
There's no error message, BUT there's no submenu anymore... It doesn't load. You can check in the code. Il tried to set "Sub Mega Menu" to tabs or columns, but it doesn't change anything.
