Bug Illustrator export to PNG from Workplan

[defaultnxonazvgc34g]

Hello every one I think there is bug with PNG export on illustrator.

I have in my workspace 5 workplan 360px * 180px when I export as PNG with no background files are exported sometime as 1501px * 750px and sometimes as 1500px * 750px.

Please if it's my mistake could you help me to understand the reason.

If you want to export in exactly those pixel dimensions, export at 72 ppi and "Use Artboards"
