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, I don't know the setup for the user reporting the problem.
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.
