My mac keeps changing screenshot format to .tiff

screen capture

I use shift + control + command + 4 a lot.
The default fileformat in my case is .tiff.
I have tried to change it to .png using these setting:

And I have tried to restart, but it does not seem to save the file in png in the clipboard which is what I'm interrested in.
I have a Macbook Pro 15¨ (with touchbar) from 2016. I'm running macOS 10.13.3.

Kind regards,
JJ

Try using Terminal, type the following command into Terminal and press Enter. This changes the file format to TIFF:
