InfoPath Dev

Hi everyone,

 I am new to Sharepoint and Infopath development. I am utilizing Sharepoint and Infopath 2010. I published a form as content type to a form library in sharepoint. I added the content type to to form library and was able to utilize the form successfully in Sharepoint.  I then deleted this content type (for testing purposes) but the columns from this content type are still showing up under Form Library Setting > Column. 

 Is it possible to delete these columns from this form library??  Please help and thank you in advance.

I believe you can just go into the settings and delete the columns from there.  Is that option not available for you?

Not for content type columns.  the Delete button isn't there.
