Using BioCheck, you can run it for All profiles in your watchlist, then sort the results by Birth Date to see the profiles that have no birth date, then do the same for the Death Date. You can also Download the results.
You could run BioCheck twice, once looking for profiles with no birthdate (you have 9) and then run it again for the profiles with no death date (you have about 150, 5 of which also have no birth date), Each time you can export the results
To run it for no birthdate, you would add b0 to the Search Text after your Wikitree ID. To check for no death date, you would add d0, instead of b0 (zero, not letter o).
The link above will load BioCheck. Change the 'Profiles to Report' in the top right to 'Summary Report', so you can see the results with the dates being visible. You also want to uncheck the Report Style Details and check the Report all profiles on the right side.
When the query is finished and results are shown, you will see the total number of profiles retrieved and can select the Download button.
Hope this helps
