 ## Known issues
 
 
-### Multi-screen Display:
+### Multi-screen Display
 
 - **Issue:** When moving the application from a secondary screen to the primary screen, the GUI may open off-screen.
 - **Remedy:** Delete the `preferences.json` file before relaunching the application.
 
-### List Treatment Command:
+### List Treatment Command
 
 - **Issue:** Extra comma displayed at the end when using the `list-treatment` command.
 
-### Incomplete Treatment Information:
+### Incomplete Treatment Information
 
 - **Issue:** The `list-treatment` command only displays the names of treatments without additional information such as the cost of treatment and duration, which were fields requested during the initial addition of treatments into ToothTracker.
 
-### Phone Number Validation:
+### Phone Number Validation
 
 - **Issue:** Validation checks for phone numbers in `add-patient` and `add-dentist` commands are currently based on 8 digits and do not verify if the phone number starts with an 8 or 9.
 
-### Filter Command Validation:
+### Filter Command Validation
 
 - **Issue:** The `filter-patient` and `filter-dentist` commands only perform validation checks on the attribute to filter by and not the keywords. For example, `filter-dentist a/phone k/myphone` will still execute the command.
 
-### Tag Error in Edit Commands:
+### Tag Error in Edit Commands
 
 - **Issue:** When using non-alphanumeric characters in tags on the `edit-dentist` or `edit-patient` commands, an "Unknown command" error is sometimes displayed.
 
-### Limited Tag Editing:
+### Limited Tag Editing
 
 - **Issue:** If a patient was initially added to ToothTracker with 3 tags, only 3 tags can be edited afterward—no more, no less. Additional tags cannot be added, and attempting to edit with a different number of tags results in an error.
 - **Remedy:** To modify tags, the number must exactly match the tags initially assigned during patient creation via `add-patient`. If additional tags are required or if tags need removal, the patient or dentist must be deleted and added again.
