View: Filter does not show the option: "Contains"

Hi Drupalers, 

I´ve got the following problem with a view: 
My view shows all content of the type: “Sold goods”. It has an entity reference to the content type “Company”. Within this view, I show in a table a field with the title field of “Company”. So far so good, my problem now is that: 

I want to filter this “title”-field which is a text field, but on the filter options there doesn´t appear the option: “Contains”. I already googled a lot this problem, but couldn´t find a solution so far

Thank you very much for your help!
