swagger is not replacing when we change the "OperationId" field in swagger doc

[Maheshcv63]

We are using this module in our Apigee Developer Portal. When the Product Owner trying to replace new swagger from product catalog with changing the value of "OperationId" field then it's appending to previous methods. "OperationId" is gives Unique method name.
Sample swagger with OperationId :
paths:
/users/{id}:
get:
tags:
- Users
summary: Gets a user by ID.
description: >
A detailed description of the operation.
Use markdown for rich text representation,
such as bold, italic
operationId: getUserById
parameters:
- name: id
in: path
description: User ID
required: true
schema:
type: integer
format: int64
