Error message when opening "Signal Logging Selector"

Hello! When I try to open the Signal Logging Editor in "Configuration Parameters > Data Import/Export > Signals" I get the following error message: The Simulink.SimulationData.ModelLoggingInfo object for model 'Model_x' contains an invalid 'LogAsSpecifiedByModels' block 'Model_xyz.../...'. The string must be a valid block path of a Model block (...). This setting will be ignored. => Signal Logging Editor does not start up.

'Model_x.mdl' is the active Simulink-Model of which I´d like to configure the signals. Surprisingly 'Model_xyz.../...' is the name and path of a subsystem of a model that does not exist any more. My active model 'Model_x.mdl' does not have any path or name alike and I cannot find this path anywhere.

Are you familiar with any problems when opening the Signal Logging Selector??

Thanks in advance! BR, Robin
