Component: 

Machine Learning Extraction

 

Issue:

Suppose you are adding any text in Mixed Case Letter in your Custom Dictionary as below:

New Delhi
Mumbai
Rajasthan
Kashmir

Above is added when doing Machine Learning and Suggestion View popup appears at Validation and we choose the Create Type option followed by the Dictionary as the Type option and then custom dictionary from the drop-down. When you will  open the custom dictionary then you will see the text entered in CAPS or Mixed Case converted to LowerCase as below

new delhi
mumbai
rajasthan
kashmir

 

Root Cause:
This is a Bug and the reason is we are converting the text to lower case.

 

Solution: 
This issue will be resolved in upcoming 2019 Release
