Strange Warnings using the newer versions of tflint

[nvima]

Hello,
Since I updated my tflint, I get more warnings, which is actually very good. For example, I gave my variables a type.
However, in many modules I get the message "terraform missing version constraint for provider". Although I specified the version in the bottom main.tf, I never had that with the older tflint version.
Do I need to add version information in each module, or have I misconfigured tflint?
The Screenshot shows a split screen. The above main.tf is the /main.tf root file and the bottom main.tf is the /modules/cloudfront/main.tf

The rule in question tries to implement this official guidance:

In other words, yes every module should have version constraints. Child modules can have looser constraints (minimum version only) while parents will often specify at least a minor version, if not an exact version.

While often you could leave out requirements from a child module with no effect as long as the parent sets them, this would mean that the module is no longer reusable or a valid root module. In order to run terraform init among other commands you need a valid root module so generally it's best to give that treatment to every module, especially if you want to run TFLint on those modules directly.
