Uneven layouts with bubble card pop-ups and separators

Hi!

Yesterday i discovered bubble cards. implementing it on one of my testing dashboards as of now.

Behind one button on the dashboard i have made one bubble card in pop-up configuration.

In that pop-up card i have made multiple separators that devide
the pop-up in multiple rooms.

Now some separators have a lot of blank space, and some not. Realy weird.
Layouts are kept as default.

Tried playing with the layouts and shorten button names but can’t figure out why i have so much free white space with some separators.
