Hello,

We are glad that we could be of some help !

Actually, for the Stretch Section there are two ways under the Elementor editor. One option comes by default from Elementor editor end and the second one comes from WoodMart Theme end which is named as [XTemos] Layout. So, if you are stretching the content wide then you need to disable the Elementor editor one and select Stretch section and content option under the XTemos Layout and then the Slider Image will cover up the whole space in terms of width & height and it will then appear fine like you want.

So, on your Site the Elementor editor Stretch sections were enabled which we turned off and enabled the Theme ones and then the Slider Images appear fine.

See these images for reference:
