A simple SharePoint custom list in office 365 has 8 columns and no special settings are enabled on it. The columns are of type choice and has 5-6 types of values present in them. The OOTB column filtering does not show all the values instead show 2-3. Can anyone help me in resolving this issue.
Example:
Column 1
A B C D E
Showing when filter drop down is selected
Column 1
B C
Tried changing the type of the columns and recreating the list by saving it as a template. Both of the methods did not solve the issue.
