RouterOS 4.17 incorrect WLAN/WDS

Hi,

Anyone encountered similar problem? Or know a solutions?

Problem: Maximum bandwidth limited to 2-3Mb after upgrade RouterOS to 4.17

It works beautifully before upgrade to 4.17. It was carrying video multicast at 27Mb previously for a range of 1.7km on 5GHz channel.
(picture attached show inconsistencies between WLAN and WDS. Normal is WLAN = WDS)
