Steps to reproduce:

1. Go to setup and rename a status that is in use and assigned to a number of tickets. As an example, rename "Waiting for Response" to "Waiting for Client Response".

2. Bug Example 1: Now go classic or compact view and select "Open Tickets". Every ticket that had the status "waiting for client response" will have completely disappeared.

3. Bug Example 2: Now go to Kanban Status mode. In this mode you would think the tickets with the old status of "waiting for response" would at least show up under "other status". But again, they've now totally disappeared as if they don't exist.

4. Bug Example 3: Go to Closed ticket view. They don't show up there either (not that they should). They don't show up under Kanban priority mode either.

IOW they don't show up under open tickets and they don't show up under closed tickets, they've just gone to some type of limbo where they don't seem to show up because they don't seem to have a status that corresponds to "open" nor are they closed".

They do show up under "All Tickets" - as far as I can see that's the only way to find them. And you have to find them one by one and change them to an existent status because there is no way to filter for them either.

Thank You
