1. Ah yes that makes sense, thanks.
2. Ok we know what you mean. Instead of changing the name, perhaps more importantly the documentation could be clearer, now it states "if that option is turned on there is a delete icon next to the filter in order to cancel it", which isn't really what it does.
Perhaps might be changed to something like:
Deletable filter : If that option is turned on, when a filter has been used, it will only display the selected filter values with a delete button. Turned off, it will always display all filter values.
But all is clear now, thank you.
