Hierarchical Select Taxonomy views : filter disapears when used

I have a view where I use a filter : Taxonomy term (Id) exposed with the settings displayed in the attachment "settingsHS.png".

The bug that I describe happens in 2 different ways : if I use AJAX, or not.

Case not using AJAX:

When I change a parameter of my filter, it changes but reload the page and the old filter reappear.
Please note that the "Remember" option is NOT enabled.

The old filter reappear all the time, even if i delete session cookies + cache, remove cache from performance, from views, etc. I always retreive the same filter and cannot change it.

(Sometimes, I get the common js error "received an invalid response from the server" if I manage to get one only filter (without depth). And it reloads just after.

Case using Ajax:

When I use Ajax, there is no reload, but the form disapear (see the pictures). So i don't know what to do.

***

I use no cache either in Views or my browser.
I managed to make it work once i believe, but if i added another filter, the bug came back.
I don't use i18n modules.
I tried with the dev version, without success.

I searched the others topics, but nothing worked (or I made a mistake).
I'm french, so sorry for my english and sorry if the answer were on the neighborhood.

Thank you.
