Unable to assign "characteristic" to product

Hi,

I just start using Hika shop today and found problem on characteristic setup in product page, i'm not sure this bug or not but pls help suggest.

Steps:
1. Setup a "color" characteristic by clicking on "characteristic > new button"
2. Create more than 20+ color values inside "color" characteristic, system able to display correctly.
3. Assign that "color" characteristic to my product in product page
4. Click on "manage variants"
5. Here system displays only 10 first color values which i previously setup in "characteristic menu", i cannot find the rest of them.

Please help advice how to manage the rest color value.

I have also attached the screen shot please check

Hi Nicolas,

Thank you for your suggestion, i have created new characteristic and assign to product, system displays full set of new characteristic values correctly

And after i tried simulate this, i have found root cause;

If a characteristic already assigned to a product, modify that characteristic's values from characteristic menu will not take effect.
Even i tried to un-assign and reassign, system will not refresh for the new value.

To solve this i need to un-assign the existing "color" characteristic, assign newly created "size" characteristic, remove "size" characteristic and reassign "color" characteristic, done, system refresh for new value
