Delayed variables update

[ivonutar]

Hi!
I have a problem with using variables in my GET request. My url looks like this:
http://example.com?var1=$var
Now, whenever I change the dashboard variable, it does not automatically gets inserted into the URL. Not even refresh works. When I change the variable to some other value, the old value gets inserted instead. The only way to force the correct substitution is by manually clicking "apply timerange" in time picker.

What might be the problem? I am using Grafana 7.5.4, but had the same problem on 7.1.*
