There might be instances when Whatfix is unable to capture the city or country value and it appears as a blank (-) in the Insights data. Whatfix enables you to exclude such blank values from User filters while [analyzing sessions](/product-analytics/docs/analyze-sessions-using-trend-insights). ![trends_session_data_with_blanks.png](https://cdn.document360.io/a268766e-d74d-4619-9613-e2472f809ffb/Images/Documentation/trends_session_data_with_blanks.png?sv=2026-02-06&spr=https&st=2026-11-10T16%3A31%3A36Z&se=2026-11-10T17%3A31%3A36Z&sr=c&sp=r&sig=RCKdfWXbrrhBJ29%2Fz7krANv80hRqYorwcUZmYc5kikU%3D) > [!WARNING] > Note: > > - Blank values might appear in your data due to the following reasons: > > a. **Late configuration of filters**: User filters, such as User Attributes, might have been configured mid-way and not from the beginning. Hence there might be blank values from the time period when the data is not captured. For example, if Whatfix was deployed on January 1 but the User Attribute is configured only on January 30, data from January 1 to 29 won’t have the attribute value, resulting in blanks. > > b. **Configuration issues**: If there are issues with the configuration of certain filters, such as User Attributes, blank values might appear in the data. > > c. **Unavailable values during data capture**: If a filter value is not available in the application when the engagement data is captured, blank values might appear in the data. > - Currently, Whatfix does not support the exclusion of blank filter values in Event groups, Cohorts, and Dashboards. ****Use case**** Analyze the number of sessions accessed from any city in India without blank values. **Data before excluding blank value**: ![trends_session_data_with_blanks.png](https://cdn.document360.io/a268766e-d74d-4619-9613-e2472f809ffb/Images/Documentation/trends_session_data_with_blanks.png?sv=2026-02-06&spr=https&st=2026-11-10T16%3A31%3A36Z&se=2026-11-10T17%3A31%3A36Z&sr=c&sp=r&sig=RCKdfWXbrrhBJ29%2Fz7krANv80hRqYorwcUZmYc5kikU%3D) **Data setup**: **Session metric:** Total number of sessions **User filter**: City Does not equal to Blank(-) and Country = India **User breakdown**: City ![trends_session_data_blank_value_removal_data_setup.png](https://cdn.document360.io/a268766e-d74d-4619-9613-e2472f809ffb/Images/Documentation/trends_session_data_blank_value_removal_data_setup.png?sv=2026-02-06&spr=https&st=2026-11-10T16%3A31%3A36Z&se=2026-11-10T17%3A31%3A36Z&sr=c&sp=r&sig=RCKdfWXbrrhBJ29%2Fz7krANv80hRqYorwcUZmYc5kikU%3D) **Data after excluding blank value**: ![trends_session_data_without_blanks.png](https://cdn.document360.io/a268766e-d74d-4619-9613-e2472f809ffb/Images/Documentation/trends_session_data_without_blanks.png?sv=2026-02-06&spr=https&st=2026-11-10T16%3A31%3A36Z&se=2026-11-10T17%3A31%3A36Z&sr=c&sp=r&sig=RCKdfWXbrrhBJ29%2Fz7krANv80hRqYorwcUZmYc5kikU%3D) Use the following steps to exclude blank values from session analysis: 1.
