I have gone through:
But it turns out that I cannot access the post-function functionality given that I am not a Jira administrator, just a project administrator. I guess one way to do this would be to remove the issue and make a new one with exactly the same content. However this is too much work. Is there another way to clear this "resolution" field?
It depends on how your Jira is set up - if your workflow has a transition that clears it, then you could push the issue through the workflow until it goes through that transition. There may be a flag set on a board for a column to set or clear it, in which case you can drag it across the board there.
But really, you need an administrator to tell you where they might be, and to get it set up correctly. You do need to engage with your admins on this one.
