In quick scan settings in the Scan section look the types of files. There are extension and such thing then just down there are a delete button and its very weird its like take a little space when there are like alot space. I hope you understand what i mean...
It isn't weird. It allows for the deletion of a a manually added file type in that section
Take a look at in the Custom scan context, where you would be able to actually add a file type to the default list. Having added it in the (select additional areas) field, which when clicked you can enter data. If you no longer want that to be scanned or you added it in error, you have to have an option to delete the entry. That is what the Delete button is for.
In that window there is room for more entries (using the add button) for each subsequent entry I guess there would be a corresponding delete button.
Nothing weird really.
The same thing is that the scroll won't work as there are no editable options that you would first have to select the Scan all files to get into that area. The Quick and Full System scans are display only on editable option in the Scan section.
