Panel do not change until manual reloading of the page

Hi,
litte annoyng isssue. I have a Combo2 panel similar configuration.
On browser Chrome, when I change one of the parameter like from of panel, page/panel do not refresh automatically, but I have to refresh manually with reload button of the browser.
In Android App, instead, panel is reloaded if one of parameter change.
Is this normal behaviour or there is a way to avoid this?

Many Thanks

marco
