“Product has incorrect parameters” error in cart

I have a problem that is driving me crazy:
When I put this product in the cart
The fields appear in this order
Length (in cm MAX: 160): 150
Height (in cm MAX: 260): 180
If I add the product after other products, these two fields swap places and divides.
Height (in cm MAX: 260):180
Length (in cm MAX: 160):150
and the cart show error
“Product has incorrect parameters! Missing field [Length (in cm MAX: 180)] in product #112”
If I add the same product several times with different measures, the order of the fields does not change and there is not error
