File Properties not showing correct data/missing data

I have this PNG file exported from AI. It's a design with colours. I exported with ' Export > Export As'. Why is the color mode in Bitmap and there is no dimension data?
A month ago with the same export method, I would have the metadata showing the colour mode sRGB with Dimensions (in inches) and Dimensions (in cm).
Anything to do with the recent update? I am already on the updated version. Please help.
