Why can't I see the Ticket Priority Icons?

[Deleted user]

Looking at my sprint or backlog dashboards, I am not able to see the priority icons for the tickets, and they all appears as the grey default icon, which does not help.

I can hover over them to see the alt-text for the icon, but this is not convenient and slows my work flow. I know that these images are set as I have seen them on screen-share for the same tickets.

I am using Firefox without any extensions enabled for the Jira site.

Expectation (obtained via screen-share):

Actual:

Edit 1:

I've checked with my support team about this issue, and they can see the icons correctly using the same browser version of Firefox.

When I opened the inspector console and took a look at the page HTML, I opened the links for the low priority and medium priority icons. The image links both came up as default icon on my end, but when I passed the links to the support team, they appeared correctly as the low and medium priority icons.

Low Priority Icon:

Medium Priority Icon:

Why would this display this way?

Edit 2:

It appears to also be the same when using Edge or Chrome on my computer; it still appears as a generic icon.

Edit 3 (12/16):

I just realized I can see Highest (Critical) and Not Set icons, but nothing else.

Very strange.

The login screen is actually the system dashboard, with whatever a non-logged-in user can see.

You can edit that by editing the system default dashboard.
