Rule not being executed

In the event logs, I have the following:
2019-11-01 09:57:04.449 [INFO ] [el.core.internal.ModelRepositoryImpl] - Loading model ‘Kitchen.rules’

2019-11-01 09:57:04.455 [WARN ] [el.core.internal.ModelRepositoryImpl] - Configuration model ‘Kitchen.rules’ is either empty or cannot be parsed correctly!

2019-11-01 09:57:04.592 [INFO ] [el.core.internal.ModelRepositoryImpl] - Loading model ‘Kitchen.rules’

2019-11-01 09:57:04.597 [WARN ] [el.core.internal.ModelRepositoryImpl] - Configuration model ‘Kitchen.rules’ is either empty or cannot be parsed correctly!

2019-11-01 09:57:05.686 [INFO ] [el.core.internal.ModelRepositoryImpl] - Loading model ‘Kitchen.rules’

2019-11-01 09:57:05.710 [WARN ] [el.core.internal.ModelRepositoryImpl] - Configuration model ‘Kitchen.rules’ is either empty or cannot be parsed correctly!

And I was reading this: Configuration model 'somefile.rules' is either empty or cannot be parsed correctly!

But maybe I should investigate further on that then
