Modal UI Elements and Grid Layout Compatibility Issues

Hey All! Quick issue that may have a known solution - I'm trying to use versions of the Modal "UI" elements, placing them as cta's for expanded info inside of standard left-right layouts (Layout 16/Layout 207) But it seems the modal has an issue with being inside the parent "layoutXX_component" - the grid element. When moved up a level to be a child of the section padding div (relume out-of-the-box "padding-section-large") it works as expected. Is this a known limitation of modals? That they will only function outside of a grid? or is there a workaround, parameter change that will help? Thanks!
