Audio file automatically NOT updated after exchange

Problem with file exchange between Cubase and Wavelab - after editing file from Wavelab montage in Cubase, it should be automaticly replaced with new version in montage window - this is stated in Wavelab Pro 9.5 help file.
But it doesn’t until Wavelab reboot.
Even if the file is manualy replaced in dedicated folder (to different file with the same name), until reboot Wavelab uses the old version of the file!
Anyone had this issue? Maybe any settings regarding peak files should be ajusted?

Cubase 10, Wavelab 9.5, all updates done.
