Negative sign on the right side of the number

Hello to all,
I’ve been using Grafana for some time and all is good, but there is one thing I don’t understand and I’m not sure whether it is a bug or not.
When trying to download values to a csv from diagram (time series), I have notices signs on the right side of the number. For example, if I monitor some value that can be negative and choose to inspect data, in the table preview negative sign is on the right side i.e after the number. Of course when I actually download these values as csv and open in libreoffice, the numbers are shown correctly.
I use Grafana v12.3 OSS on the Linux Mint 22.

Is there some kind of setting somewhere to correct this? It is rellay strange that negative numbers are shown this way.

Thank you!

To answer my own question I have found that the issue is resolved if custom unit is chosen, for example “cm” for length is entered:


But still I do not understand why the original behavior is to place negative sign to the right. I have checked and the data in the database are of float type.
