Issue with rating model configuration

Summary:

Content (please ensure you mask any confidential information):

Hello experts,

we are configuring rating model to be used in overall performance rating (performance documents). Basically, if the overall score is between 0 and 1,5 the Rating level should be 1, if it is between 1,51 and 2,69 it should be 2, if between 2,7 and 3,5 it should be 3 and from 3,51 to 4 it should be 4.

However, we cannot enter decimal values in the attached section. The only way is to manage by multiplying values by 100. We prefer to use decimals.

Is there a way to replicate the expected behavior?

Thanks in advance for your time!
Regards,

Valerio
