Marko,
Originally it was set to ‘link’ and I changed it to ‘icon’ when playing with the settings whilst trying to fix it. As per your testing, it does seem to have fixed the issue. I wasn’t sure though if this was the correct solution since ‘icon’ and ‘link’ are not very intuitive since I don’t have an icon.
Anyway, your answer seems to re-affirm the correct solution. I did notice though whilst fiddling that the mobile menu got centred somehow – I had to add a small piece of CSS to left-align it again.
Thanks for your swift answer.
Regards
Alan
