I could replicate your issue and it seems this is a simple stylesheet issue.
I guess it was just missed to add additional rules if you place another inner section inside the carousel.
The problem here is, that the carousel item gets the same width as the inner row as the same CSS rule applies. So the carousel content width is exactly 50%, as you already mentioned.
Should be fixed in an upcoming release. Here is a temporarily fix:
.grve-flexible-advanced-carousel[data-items="2"][data-slider-loop="no"] .grve-element, .grve-flexible-advanced-carousel[data-items="2"][data-slider-loop="no"] .grve-inner-section .grve-inner-section {
width: 100%;
}You might adjust this code if you change the amount of carousel items.
Please remove this snippet after the update. Hope that helps.
