Super strange Issue with my Kanban Board

[Anastasia Florescu]

Hello,

I googled a lot, but nothing helped. 
I don't know what happend, everything was fine with my quick filters. 
fixVersion = 9.10 this quick filter is helping me to see on my board tickects from version 9.10 and ect.
Now, i can't see it. Something messed up and i can't figure it out. I have quick filters, Columns but everything is displayed incorrectly on the board. From 3rd picture "Board" everything should be scattered in columns and i should see another items in other columns not only in done.
Please take a look at my pictures and help me find out the reason and fix it.

Also,  how to delete saved filter (the fourth photo)

Please, help me!

There are might be one of the following reasons.

Reason 1:

I do see that in the Kanban board you have selected version 10.0, related to that version 6 issues were completed and you can see those issues under "DONE" column.

If you want to view all the issues, deselect all "Quick filters", so that you can view all the issues.

Reason 2:

Did you check this field under"Configure board" ?, if version 9.0 issues are older than 2 weeks it won't display. Please adjust this field as per the version 9.0 

Coming to other question, how to delete a filter...

Open the filter in a new tab and under extreme left corner, select the relevant filter and click on "Delete".

Please take a look at the below screenshot.

Hope I answered your questions, if so please accept my answer.

Post if you have any further any further questions on this.
