Can not hide signature component on the salesforce Field service document builder template

Hi All,    I have a require to generate service report in two languages. in one language 3 singatures are needed and for the other only 2 singatures are needed. I am trying to use 1 single template with component visibility filters to hide 1 signature block but when I generate the service report on the SFS mobile app it shows me 2 signatures but requires 3 signatures to proceed further. Has any one tried to do it? any tips or suggestions?
