Content creation

I've got a main scene with several buttons that lead to other scenes on it.  One button is displaying the plus sign rather than the arrow.  I've deleted the destination scene and recreated it.  Then I've gone back to the main scene to add a Go to Scene navigation and the button still comes up as a plus sign and I can't find where to find it!

Can anyone help?

Thanks so much!

First of all thank you so much for such a wonderful material.

i just joined the community and I take advantage to greet everyone in here.

now passing to my topic just  a quick question I have created a content I  drag and drop but I can't remove the background. to be more specific.

I have created a tree where i put apple and my son has to drag and drop them into a basket. but the apples they have a white background as a pictures. not like a fruit in the tree.

Hi, 

I created some stuff in moddle and now I would like to know if it is possible to open it in my personal H5P account.

Regards!
