Content creation

When I make the lecture presentation full screen, it adds 3 px height and is not visible. The full screen html code is as follows.

<iframe id="h5p-iframe-33" class="h5p-iframe h5p-initialized" data-content-id="33" style="width: 1920px; height: 3px;" src="about:blank" scrolling="no" title="Title" data-original-w="730" data-original-h="1" frameborder="0"></iframe>

Is there an automatic height setting in this 3px?

Can anyone tell me if it is possible to trigger a hotspot (the correct one) on one screenshot which then navigates to a new slide where the user has to find the next hotspot?  The idea being to test the user in an assessment - i.e. where do you click on the screen to access x?

In the past I never had this problem, now, looking in an old course, in the pages where are 2 or more H5P, only first is displayed, the others show only the link.

How can I solve this?
