Be careful with this one...
I've been caught out by this before.
It is the question of whether a motion must have a seconder (or indeed 4 for a recision motion) at the point of submission or at the point where it is debated.
I would contend that it is at the point of debate since how can anyone NOT be predetermined if they second a motion prior to debate?
There was a long discussion about this recently.
The point being, whether your motion properly required 1 or 4 seconders, that cannot be determined until AFTER debate so the chair would have been wrong to dismiss prior to debate on the basis that it hadn't received sufficient seconders....
Sounds to me like you're being tucked up by your clerk & chair.
PS - to answer the question is it reasonable to expect the clerk to assist / advise - I'd be at something of a loss to describe what their job actually was if those 2 elements were not primary outputs...
