Decimal places showing after number (Facts)

I am using Sydney FP: Facts on my site - and the numbers are rounded. However, on mobile it is showing a long, decimal place after the number? (this is not happening on desktop?)

I am seeing the same since 3 or 4 days (WP or theme update?) on both Internet/desktop and mobile - this is weird to see a umber of people, countries or sectors with decimals. How can I prevent this ?

We will add an option to disable autoformatting. It’s dependent on your browser’s language and what the standard for your language is. For example I see both your sites fine on both mobile and desktop, without any decimal places.
