I'm using Joomla 3.9.28 (yes, I know, I haven't upgraded yet). I run a linguistics site, so have added dozens of custom characters to the Custom Character Map. After JCE Pro update to 2.9.18, they no longer show up under the Insert Custom Character button -- only the built-in default characters show up.
They are still there in the Editor Profile Plug-in Parameters for Custom Character Map -- they just don't show in the editor.
Is there something I need to do to get them back, or is this a bug?
