Bug of placing barriers in OpenBridge 2022 R1？

Hello there.In OpenBridge 2022 R1，I would like to place a barrier along P_4 point of the deck.But when placed,barrier can't follow P_4 point finally.It seems the work point of barrier always recognizes the upper surface of deck,just like following pictures and video.

However barrier can be placed correctly following the selected point of deck in OpenBridge Modeler CONNECT Edition - Update 9,like the following picture. Is it a bug of placing barriers in OpenBridge 2022 R1？

Here two models with different OBM versions are uploaded as attachments,since I hope this problem can be solved as soon as possible.Thanks!
