problems with numberFilterType option 'condition_operator' => FilterOperands::OPERAND_SELECTOR

[raynermenendez]

im using numberFilterType and i want to use the option 'condition_operator' => FilterOperands::OPERAND_SELECTOR but when i trie to use it my number field was displayed without any options(Is supposed to show a combo box or something like that?) in the template and when i submit the form i got the following error:
Warning: array_key_exists() expects parameter 2 to be array, null given
I used other field options like OPERATOR_GREATER_THAN and works perfect the problem is when i trie to use
OPERAND_SELECTOR.

my field configuration is
->add('presupuesto', Filters\NumberFilterType::class, array('condition_operator' => FilterOperands::OPERAND_SELECTOR)).

I will appreciate any help
thank you and sorry for my english i know is bad
