[Resolved] Custom link label not translating

Background of the issue:
I am trying to translate custom link labels in a mega menu on my WordPress site using the WPML plugin. I have a theme called Uncode and have set up a mega menu with custom links that serve as category labels. I have used string translation and WP Menu sync as per the tutorial. The issue can be seen on the page: hidden link

Guys, I beg you to finally reply my ticket.
I have contact you at least two or three weeks ago when I launched my site!
I have a theme called uncode, there I have set up a mega menu. Now in this mega menu i have custom links that don't really tako you to anywhere, they are really there just to signify a category (so there is only a label). Those two custom links are called "Starinski predmeti" and "ostalo" in slovenian language. And no matter what I do they don't translate into english in english page. I have already used string translation and WP Menu sync all according to your tutorial. I doens't work. And I very angry, that you guys are taking a very long time to even reply. This is not my first ticket. If I pay 100€ for your plugin I expect to get help In a normal amount of time. I needed your help when the page was lauched which was 3 weeks ago.

In the Menu sync list my two string that I am trying to change are written twice in the same row. One is colored in the dark green and on is colored in blue. According to your legend under the list that means "item has changed position" and "Menu option will be updated" but the updates don't happen. I have cleared cache etc. ž

I understand you guys are also busy with other tickets but please understand that I need to get this sorted out as my client also expected things to already be finished when the site was published. Now it's way past that time, and we need to have this fixed as soon as possible.

Thank you

Symptoms:
The custom link labels 'Starinski predmeti' and 'Ostalo' do not translate into 'Antiques' and 'Miscellaneous' on the English page. In the Menu sync list, the strings appear twice in the same row, colored dark green and blue, indicating 'item has changed position' and 'Menu option will be updated', but the updates do not occur.

Questions:
Why are the custom link labels not translating despite using string translation and WP Menu sync?
What do the colors dark green and blue signify in the Menu sync list, and why are the updates not happening?
