Problems with png transformation for Safari

Hello community,

I’ve encountered a weird bug with png’s. Some of them, probably only those that use a greyscale model, won’t show up in Safari, but instead look black. Sometimes you can even see how Safari loads the picture correctly and then switches to a black image. However the problem is inside the png. And it is not inside the original png, it only occurs through the formatting that Squarespace does with the picture. I can track it back by downloading the picture and it looks good in every program, except for Safari; however if I save it without changes but as a colour RGB, Safari opens it well. I upload it again and Squarespace changes it again and it becomes black again. Can anyone think of a solution to it? Both png’s are attached. Thank you very much.

I’m sorry. Uploading the pictures into this forum converted them once again… So there is no difference anymore between those png’s.
