It's not a problem, I'm just wondering, why the difference ?
The small value is the file size and can vary depending on which format and compression the image is saved.
png in Gimp is saved with a high level of compression but is lossless. What you export is what you get back
Export as a jpeg and that is a 'lossy' format and depending on the amount of compression amounts of image information is lost.
The value you see at the bottom of Gimp is the size of the image being processed is not compressed and will includes any extra layers etc that might be lost when exporting to a png or jpeg.
That is why the default 'save' in Gimp is Gimps .xcf format which is lossless and keeps all layers, masks, transparency which will be lost with other formats
