I don't know if this is this is the right place, but the flow page of the node node-red-contrib-ocpp2 seems broken, because there ist a h2 Element in front off everything. The links to github etc. are behind this element. When i delete the element in the developer tab (f12), Everything work as expected.
Yes, that is the issue. It clashes with a CSS class used by the cookie-consent banner module we use. I did have a look to see if we could improve the namespacing of the CSS used by the module, but there was not a quick option to do so. It will require updating the module to their latest version, which is a complete rewrite and not a drop-in replacement. I'll get to it eventually.
