Kanban Page display missing top of page

[Bob Sellers]

Added three columns to an existing Kanban board. Now when I view the board, all content above the Quick Filters section is no longer displayed on the page. CSS? It flashed the page properly then the top section disappears.

Tried removing the default sub filter and the page displayed properly. Now I have issues that are no longer appearing on the board but appear in the issues.

I realize I can undo what I did and the page displays as expected. I am working to fulfill a PM's request by adding the addition columns. Is there a limit on columns for Kanban boards?

I disabled all the plugins and add-ons for the browser and it appears to be working.

Hi

random suggestion 

have you hit the presentation mode shortcut key ‘z’

I hit 'z' and the down arrows displayed at the top right but it did not change the display.

the line above the quick filters section is the bottom of my browser's bookmarks bar.
