MultiVariant Custom field Unable to Add more combinations

[john-doe]

Greetings.

I have an issue with the Multivariant Custom Field.

I have 3 lists but despite i have more than 135 children products, only allows me to set 125 combinations and when i need to set after that numbwer after i save those combinations are not saved. I have to name and set the price of the remaining products by hand but despite this i stiil i'm unable to set combinations. Is there anything i can do to raise that roof?

Thanks in advance.

My store is xpeditiontours.com and the product is this http://xpeditiontours.com/en/transportation-detail (see below the tables what i need to set in)

It got worse. I finished to make the full lost and they are 167 children.
I delete the Multivariant custom field and make a new one. Now it's not accepting the custom field and no error shows up
