Monitors rotate 90° anti-clockwise when going into ClamShell mode

[Jackaroo]

Hi All

A newbie here, but hope you can help me with a dilemma

I have previously been using DisplayLink Manager v1.12.4 successfully in clamshell mode with my MacBook.

Today, when my Macbook screen is open my 2 separate monitors continue in the correct orientation.

When I close my Macbook and go into clamshell mode, the image on the 2 separate monitors auto-rotate 90° anti-clockwise.

It just started all of a sudden today.

Have done various Google searches and searched this forum, but cannot see a similar issue/solution.

Would appreciate your thoughts and possible solutions.

Many Thanks!
