Power Profiler 2 measures ~15mA after a measurement spike even without a load connected

Can my Power Profiler 2 be faulty?

It does the following in both source meter and ampere meter mode. I start to measure and it shows some microamps current that's expected from the soft latch circuit. Then I turn on the measured device by latching the circuit and the profiler shows approximately 100 mA of current, that's also expected. Then I turn off the measured device but the profiler does not return to the previously measured microamps, but instead is shows approximately 15mA of current even if I completely remove the load from the profiler. I need to switch modes on the profiler or turn it off and on again to be able to measure the expected microamps again. Turning the power output off and on again or stopping and starting the logging do not fix the issue.

Power Porfiler software verison is: 4.3.1
I cannot tell the firmware version od the PPK2, I could not check it anywhere. But at first connect an update was performed.

Thanks any help in advance.
