Photoshop 2017 PNG Export adds weird objects

I think this error only started to occur for me after i updated to the 2017 version of Photoshop.

Everytime i try and create a logo/icon that has multiple layers, some space that needs to be blank (png) and more, when i save it as PNG, no matter what option i check it adds all kind of weird shapes and lines that should've been hidden or not even exist in the first place.

In the first picture you can see it in it's original form (when uploaded to the internet, or opened in PSD format.)

In the second picture you can see it in it's most occuring form, when i'm importing it to microsoft Office, another photoshop project or hell even illustrator shows this. This example isn't even the worst, sometimes when designing certain logo's i get the most weird lines running straight through my logo, a black stroke that is insane and ofcourse the white background altho there is no white background active in the PSD file, and i'm saving it as PNG, also i didn't even use strokes so the black stroke really surprises me.

ANY help would be awesome, as i'm really struggling with it at the moment. =/

I'd like to add a potato here, but this isn't 9gag.
