Impossible to center images, doesn’t works ?

Hello ??

I notice a problem with the plugin, that I did not have before the last updates : my images are not center.

The option is however well activated in the settings of my gallery.

I tried all the alignment options, the images get always stuck on the left.

Would it be possible to fix it in a future update?

Thank you in advance ??
