Hi,
Could you please check if a "release all" can help or not?
I mean press "release all" with the user who previously reserved the affected element, then use "send&receive" with the others.
If it does not help, please also try to reserve the affected element again with the user who see it as "free for reservation", then try the "release all".
Please let me know the results.
Best Regards,
Istvan
