Hi everyone, 

I'm testing Odoo studio by inserting custom fields. It happens that if I delete a field and then recreate it with new characteristics, the deleted one remains in a sort of database. Now I have a series of duplicate fields, isn't it possible to eliminate them completely?

Let me give an example: 
I create a select field called "VAT number", then I realize that I need a checkbox, so I delete the select and create the new checkbox field "VAT number"

If I then have to create a rule or a related field, I find "VAT number" twice, but one of the two has already been deleted.

Thanks for your help
Linda
