so we have a form where we are asking a question where the user is able to submit multiple answers in a check box format, what im doing is using useState to hold the answers to the question, then validating the size of the array to set the button either disabled or not. Currently you have to check and uncheck an answer for it to even appear in the array and checking it multitple times still adds the same answer over and over again in the array instead of deleting it not sure what im doing wrong here.

Here is what happens when i click an option or multiple
