Getting only the value of "Buy" on Openinsider

After experimenting things, I found out that the problem may be because of the wrong filter performed back in Openinsider. I performed a new filter back in Openinsider website and managed to get the expected result. You might have just forgotten to click the search button on Openinsider site when you input the filter values.

Regarding your concern about the other QUERY returning "No Purchase" I suggest that you post it as another question as you might encounter issues chaining it to the concern addressed by this answer.
