When displaying json file, I see the strange JS: labels shown in the attachment, which are there only for numbers ending with ".0".  I tried different instances of the same data, with different numbers, and the JS: label only appear with those numbers.

I can see no reason for this behaviour, so I am signaling it as a bug
