Multiple features disappear, forced to reinit the module to show them again

[leMich]

Hi,
i want to use your module with PS 1.6.1.3, but the features comes back to the original view when i clear the cache of PS !
If i reinit the module, i can select multiple values again as expected but all previous values are lost.
Any solution?
Thx.

The same problem occurs in my PrestaShop 1.6.1.10. I must use 'Reset' to show the multiple features again. I have to 'Reset' it at least once per week.
Please fix!
Thx.
