Layout Not getting Called In Custom Module

Question

I have developed a custom plugin that used to add a custom made shipping method. For that custom made shipping method I had override the existing templates. It was working fine but changing the server has caused some problems and now my layout files are not getting called(i.e my html is not getting loaded.). However, I have deployed the same code on localhost and everything is working as it should be.

I have enabled the template hints and there I can see that on localhost my files are getting called but on live the default templates is getting called. I have compared the files for any changes but everything is the same except the behavior. I am attaching the respective xmls here along with this code.

Answer 1

The Issue was that another third party plugin was overriding my template file. When I disabled that plugin, everything started working fine.
