If you read it in context, that means:

"the ones who do seem compatible have problems like the above"

There are a lot of incompatible guys trying to make me like them and hoping they can magically "make it work", and the ones who do seem good have problems like the above, and I feel a need to cut it short to prevent dysfunction.

You can be dysfunctional and incompatible, which is a fail. Or you can be functional and incompatible, also a fail. Or you can be compatible and dysfunctional, still a fail.

The only thing that's not a definite fail is compatible + functional.
