Gallery Stack 3.10 grid options unavailable

HI,
cross posted to the rapidweaver forum

RW 8.6.2 Foundry 2.0.1 Gallery Stack 3.10.0

I have just purchased Gallery Stack 3 to make a portfolio site using Foundry.

Gallery stack only offers one grid option [Bootstrap 4(Foundry)] in the dropdown menu.

The option I specifically require is the masonry grid.

With the bootstrap 4 option selected the select lightbox option doesn’t work either.

Any Suggestions

thanks

Which options do you see?

Then continue there.
