Average formula rounding off to lower bound when using on Score type column in Models

I am using the Average function on Metabase Model column of Score type and the result of the aggregation is a rounded off value.

As shown in the screenshot below, the average should have been 4.6 i.e. 318 divided by 68 but the Average function returns 4 i.e. rounded down from 4.6

How can I get the original values?

Troubleshooting info?

Hope this helps,
