Having trouble with IF NOT statments work in Sheets

this might be an easy fix but I just can't figure it out. I'm trying to get this IF statement, if the cell is not FALSE to return value, else to return a certain string. I've tried a couple of ways but I can't make the right combination. And I have a similar issue with excluding the FALSE value from a UNIQUE search statement. This is the sample. Sorry if I'm missing on smth very obvious
