Vimeo embeds within GenerateBlocks grid

Hi there,

I am using Generatepress theme, and have used a GenerateBlocks Pro grid to display Vimeo embeds side by side. Some of the videos spontaneously appear with spacing above/below, so that the two videos do not appear in alignment. (Left-hand video in example linked to is fine, right-hand video is dropped down out of alignment with spacing above and below it).

I have tried recreating this multiple times and not sure whether I am doing something wrong in GeneratePress/GenerateBlocks, or whether there is an anomaly with the video itself?

Any help pointing me in the right direction for troubleshooting most appreciated.
