As system, in the REST API, whenever exporting test runs based on Test Plan key, only information from the related Test Executions should be exported.

The current endpoint (https://confluence.xpand-addons.com/display/XRAY/Export+Execution+Results+-+REST) provides the testPlanKey which serves as the means to obtain all the Test Runs related with those Tests, no matter if they are in that plan or not.
