Eliano,
You likely added them to both of your catalogs (the ones I can see). Both are set to "Add" which means when you add an image, it will be added to all catalogs that are selected for "Add".
Right, my mistake! Now will be hard to delete them to one catalog...
It shouldn't be difficult unless determining which ones are duplicates. If all images are duplicates then the following should work:
Uncheck both checkboxes (Search and Add) from the catalog that you want to continue to have those images. Perform the search again. Select the images. Remove them from the catalog. Then uncheck the Add checkbox from the remaining catalog. Now set the Add and Search checkboxes on the first catalog.
If you don't want duplicates, you should only ever have one catalog set for "Add".
