In the generated standard compensation statement the rating is showing as the number value while in the form you have it showing as label value.
Reproducing the Issue
In the Compensation Template set your Rating Label Format as 'Text' or 'Number-Text' > Launch a Comp Form > Complete it and then Generate a Statement > Rating field value is showing as Number despite of the selected Rating Label Format.
Currently Standard Compensation Statement only supports numeric value.
There is already an open enhancement request to support 'Text' and 'Number-Text'. Engineering Team will be conducting analysis on how this can be achieved.
If the statememt rating value as 'Text' and/or 'Number-Text' is significantly needed you may opt to have a Customized Compensation Statement. Please check this article 2084848 - Statements - Costs and Process to Personalize Compensation Statements - Compensation.
