Two filtered galleries

Hi,

First of all, thanks for this plugin.
I have two galleries on my page and I have a problem with the filters.
Indeed, the filters of the second gallery affect the display of the first gallery. However, this is not the case for the opposite.
Even if this is not the expected effect, I could understand that the two galleries influence each other but in one direction only, this is a strange behavior.

Could you help me to have these two galleries quite distinct?

Thank you in advance
