Power Query - Stop trying to Convert to number

So I'm running a query, and it tries to convert certain columns to number, because they are numbers. However I dont want them to be number, I would like them to be general, as it causes errors and will not return the data. Even when I try to convert to text, I still get the error. How do I make the query stop trying to convert the column, and let me just choose what it is?

That is not even a step yet. In the source data step, just the first load, it is already trying to convert them to numbers, so the data doesn't come into the query and only shows error, if that makes sense.
