I have created couple of custom fields in Jira (server version 8.13.0; 4.13.0 for service desk, same issue with test server, version 8.14, service management 4.14.0) - for example "select list (multiple choices)" or "select list (cascading)".
When I display then in my Service Desk project to the portal, they seem to not work. or not presenting the values, so the seems to be not working, box only gets dark like in the picture:

Later I found out that if I go with the browser zoom to at least 67% (Chrome, FF, Edge latest versions), it is actually displayed somewhere in very bottom of the page, like in the picture:

(Never mind the blank space, I just removed other stuff, not relevant).
Anyone else had similar issues, maybe some suggestions?
BR,
