Hello,
Though I am not an expert in this and might be wrong, Google is cutting out the transparent part of your Image (from left right above and below) and just showing the small text remaining, and above all that, its showing in squished circular format, so it’s distorted.
Now what you can do about it that add your own background shape behind “P13”, like a circle. You can see that, google itself has done it (White circle being G in favicon it).
In a nutshell, try having your graphic that is inside a PNG in a 1:1 ratio too, since your P13 is in rectangle shape, it was shown as that.
OR
You can skip all that and just use a JPG.
Hope this helps.
Thank you so much for your Feedback! Already changed it like you said. It still appears squished in google search but I think google needs time to crawl!?
Yes indeed, Google crawls site and update in sometime, might take a few days.
