Reason for services.yml override is not reflecting correctly for FO controllers?

[Dinu SK]

I have created one base module for a payment module and a dependency module for overriding the base module using services.yml.

Below is the services.yml created in the base module
 

services:
  _defaults:
    public: true
  ignite.new.checker:
    class: Ignite\Src\ignite\helper\Checker
    shared: true
  ignite.frontpaymentoptions.paymentoptionswrapper:
    class: Ignite\Classes\ignite\FrontPaymentOptions\PaymentOptionsWapper
    shared: false
    

And below is the services.yml used in the dependency module 
 

services:
  _defaults:
    public: true
  ignite.new.checker:
    class: Override\Src\helper\Checker
    shared: true
  ignite.frontpaymentoptions.paymentoptionswrapper:
    class: Override\Src\FrontPaymentOptions\PaymentOptionsWapper
    shared: false

Currently, I am facing an issue with FO controllers that is when I try to get a service "ignite.frontpaymentoptions.paymentoptionswrapper" inside hook hookPaymentOptions, it always gets the class from the base module, not from the dependency module. But when I debug the service container it shows the override class "Override\Src\FrontPaymentOptions\PaymentOptionsWapper". I cleared the cache from the admin advanced parameters option.

Does anyone know why the FO code does not reflect the override class?
