Hey @Ana_Bea_Studio ,
Can you try creating a new slider and add an image in the slide and set the image with a fixed width and height based on your design requirement and try testing this out with each image that you want on the slides?
The images currently used in slide are of large dimensions and do not have consistent width with respect to other images, so that might be hampering the slide width calculation and providing this weird experience on the site.
I was testing your use-case with slides and when I set a specific height to the slider element, let go of the ratio settings, have the background image to be set to ‘Cover’ and remove any other specification from each slide, the slides do work on the published site without skipping.
Can you try testing the slides (without any interaction) with some image and specifications first and try introducing each image with specific width and place it out of the grid at first and see when the issue crops up?
