User says the problem goes away when he try to access the page as an anonymous user. He has also tried to turn off all gadgets. I have also checked if I can recreate the bug with turning on or off gadgets, but to no avail. I also tride to test with some of the beta functions, but likewise, nothing happen. My browsers during testing was Firefox and Chromium on Ubuntu 17.10, the user reporting the problem uses "Chrome and Firefox, 64-bit".
In the users own words
"I'm having trouble filtering. It just 'jumps back' when I click on the page. I think it worked well at an earlier time."
"It works as non-logged in user, so there is certainly something about my settings. What's happening: I'm checking for a filter; It is on the list and in the background I see that the filter is switching on; When I click somewhere on the page to get the drop down menu, the filter setting disappears."
"I turned off all settings(?) but to no avail."

I will ask again for the browser, OS and version.
