Minor - no error indication on wallet creation when user accidentally inserts two+ of the same words

[PARTimprovert]

When i created my new wallet, i accidentally inserted the same word twice in two different positions. Words are 'correct' but one of them is in the wrong place obv. and needs to be replaced by another one. No error indication is displayed when trying to go on with the wallet creation process by trying to press continue. Three+ of the same words neither give an indication to the user he did something wrong but the event of a user inserting the same word three or more times seems unlikely.

I think the users mistake could easily be pointed out to him/her with a simple error check/validation?
