Substitution path will not be resolved properly if path is used in "included file"

environment: .net 4.8, VS2022

The object path is evaluted in a wrong way if evalutation in a included file

Let's image following main file:

import-rules
{
	default-data-first-page = "1"
	default-data-last-page = "9999"			
	default-data-converter = "buildin"
	default-data-ignore-case = "true"
	
	default-range-tolerance-x = "4"			
	default-range-tolerance-y = "0"

	default-data-field-name = "Value"

	pdf-import-rulesets =
	[
		include required(file(".\\PdfImportRules_TWDInvoice.conf"))
	]
}

and the file to be included:

{
	has-id = "{789C90B4-25A3-46C9-A1E2-1C0DF6352783}"
	has-type-id = "ExternalDocumentsType.TWDInvoice"
	has-friendly-name = "TWD Rechnung"
	
	detection-rules =
	[
		{
			has-id = "{403840A8-6C18-4A79-936A-8C944A36E9D2}"
			has-friendly-name = "detect: Rechnung"
			data-converter = ${import-rules.default-data-converter}
			data-ignore-case = ${import-rules.default-data-ignore-case}

			data-is-static = "true"
			data-type = "string"
			data-content = "rechnung"
			
			data-range-tolerance-x = ${import-rules.default-range-tolerance-x}
			data-range-tolerance-y = ${import-rules.default-range-tolerance-y}
			
			data-on-page = ${import-rules.default-data-first-page}
			data-start-point-x = "339.05"
			data-start-point-y = "656.11"
			data-endpoint-x = "384.87"
			data-endpoint-y = "657.42"
		}
      ]
}

the parsing gets an exception:

Unresolved substitution: import-rules.pdf-import-rulesets.import-rules.default-data-converter. At path 'import-rules.pdf-import-rulesets.import-rules.default-data-converter', line 11, position 25.

Putting the content of the included file directly into main file (and remove include statement) resolves all data as expected.
So, if a file is included, the path is not evaluates as ABSOLUTE but as relative path and is concatinated. In our example the
"import-rules.pdf-import-rulesets" part of path is wrong
