Empty space appears when gallery added

Thanks for reporting the problem.
I think I found the reason of the problem, it’s because the slider’s height is set to “Adapt to content”, in slider options. But I would be interested to have your export of the page to test this locally.
Can you export your page and send it to me with this form as a zip file ?

thank you

By using a form you sent to me there is no option to add an attachment.

This is fixed, you can attach your zipped ( .zip ) export now.
Thanks

Done.
Please tell me if is there an option to set the speed of slider transition-duration?

There’s no option to set the speed of the slider transition duration in Nimble slider module.

It is ok now. Thanks.

Perfect. Thanks for the feedback.
Set as resolved.
