I ran into this issue to when I used the nestable slider and custom breakpoints, what I found is in the JSON of the options it was adding the settings in a breakpoints option, but not changing the default options any longer… my fix was to change options type from “Default” to “Custom” and applying my own JSON object:
Notice specifically I had to update the top level “height”, and then over write the “height” object again in the breakpoints array… (this was just a copy of one of my jsons) but I do have an example of getting the multiple slides to work correctly here: The Need for Change - Diabetic Foot Care - Podimetrics
Just make sure to edit your “perPage” option in the top level and then again for each breakpoint below it.
I am having the same issue with breakpoints. I go with mobile first and wasn’t able to setup necessary amount of slider for every breakpoint. Hopefully this will be fixed soon …
