Not load dynamicdropdown_miltiple

After save my dynamicdropdown_miltiple TV and reload page, TV can`t load fields and load are after reselect dynamicdropdown_miltiple in TVtype.

I had the same problem. This is due to the fact that the TV type in the database only 20 characters. It was necessary to increase the size manually. Now everything is stored properly, but this TV type does not output any results at all. Please fix it.

My parameters:
name:category
type:dynamicdropdown_multiple
Parent Dropdown: no parent
Dynamic Dropdown Group: cat
Where Clause: {"parent":"18"}
