Is there a reason Foundry loads two jQuery libraries?
If you select the Foundry theme and just have a plain Stacks’ paragraph stack on the page, there is a single jQuery (jQuery.min.js) loaded. It looks to be v2.1.4. This seems to be loaded by the Foundry theme.
As soon as you add the Foundry base stack to a page, you get a second jQuery library loaded (jquery-2.2.4.min.js). This appears to belated by the Foundry stack.
