Problem with the idiom selector

When I enter into my site, I have an Age Gate with idiom selector.
If i enter normaly with spanish it works good, but if I select the english gate and then I choose “Yes, im older than 18”, it works, but when im in the english home and then i choose spanish on the selector, I go again to the Spanish Age Gate, and the after I choose “SI” the idiom selector “crashed” and never change again to spanish version, it keeps into english.

I think that this can be a “bug” or something with the idiom selector.

Please give me a solution or an answer.

Best regards.
