No, that's the correct form

.
The problem is that the online form is generic and is pretty much the same for all visa types, so it has questions on it that don't seem relevant to a spousal visa because they're aimed at people applying for say, visitor visas, where you do have to show employment to return to.
So, you just have to fill out your employment details anyway, even though they cannot be considered for the visa.
And when it asks how long you will stay in the UK, you put either 'permanently' or 'indefinitely'.
Also, when it asks for parents' details, it means the applicant's parents, not the sponsor's, even though it reads like they mean the sponsor's parents.
