Sensor value (CO2) not aligned to other sensors value text

Configuration
1

Hi, it is my first post so forgive me if I missing section.
I got a sensor on CO2 that is a great value and for that is not aligned to other widget sensors text.
Is there a way to reduce this value in percentage so I can have my Hadashboard in good way aligned same text same line?
Thanks

I found in widget option: shorten:1 but it does not works, the actual value is around 600 ppm.
Where I’m mistaking with shorten: 1?
Thanks
