Description

The generated model has a wrong name, when the model comes from another file.
E.g. in my example the model is named AddRequest, but should be named UserDto

openapi-generator version

I am using 7.10.0. It is somewhat of a regression. This issue is not happening when I use openapi: "3.0.3", but it is happening with openapi: "3.1.0"

thanks for reporting the issue

as a workaround, you can try the modelNameMappings option to have complete control of the model naming: https://github.com/openapitools/openapi-generator/blob/master/docs/customization.md#name-mapping
