I recently reforged a level 70 vengeful wind fist weapon and received a primal ancient version which has approximately 1/6th the damage of its ancient counterpart.
my query is weather or not this is actually a display error or an actual damage value and also do primal ancient not have forced maximum damage values?
I have included a screenshot of the side by side comparison

Seriously, read the stickied topics!
- My Weapon Went from 2000+ DPS to 400
Go back to the mystic and enchant the +xxxx-xxxx element damage back onto the weapon and NEVER roll this affix off ever again (unless you want to be zdps). The +xxxx-xxxx elemental damage is a main component for the damage of the weapon.
Never change the first of the first damage stat. NEVER.
The point is not that you did or did not enchant the Weapon Damage off.
The point is:
You can test this by re-rolling the Percent Damage on the Primal to the maximum Weapon Damage.
Best case scenario would be to have both, Percent and Weapon Damages on your Primal. Unfortunately, you will have to sacrifice one of them.
And, just in case the Weapon Damage does less Damage, which I doubt, you can always enchant Percent Damage back. (As you said, it will always roll max stat).
Example:
i moved this thread from the bugs topic. sorry i’ve been in diablo 3 for a little over a week(a friend of mine has recently rejoined from years ago so he was uninformed on this issue as well but has helped me progress into getting primals)
Plus the searches i did were far less than helpful and i did not know how[or where] to dig this info you’ve shared up(I.e. i didn’t even see sticky topics on the bugs pages to know i should read them)
thank you and all the others who were willing to correct my misinformed bumbles
A last and little information:
Don’t care about elemental damage on your weapon 
Now that you know about not rolling off the elemental damage, you would have been better off rolling off the vitality into 10% damage. That would have left you with a weapon with 10% damage, dexterity and 24% area damage. The more paragon you have, the less important main stats like dexterity and vitality become as you can allocate paragon points to make up for it being missing on gear, in order to get offensive stats that you can’t otherwise increase.
YES! This is very important!
If the Property says: +% to [Element] Skills, then the Element type makes a difference. You would want to roll the Element type your build is using for main Damage.
But, Weapon Damage range does not matter what Element Damage is specified because it’s just extra Damage. A LOT of extra Damage, as seen in the image I embedded above.
