I have created a custom field called "Deploy To". This field has been in use for years, and renders correctly on issues.
When trying to use this field in a basic or JQL query, the field will not show up.
The most common resolutions for this issue involve tweaking the field's context, as its usually restricted to specific projects or issue types and the user needs to add this criteria into their query to gain access to their custom field. This is not the case for me.
The only (and default) context i have for my custom field is for "any issue type" and "Global context" (all projects). So the permissions are as open as they can possibly be.

Example of a basic query (Deploy To custom field is missing..)
