display issues with LiveControl_2_1_31

I have the following trouble with LiveControl_2_1_31 on my iPad.
I use an wifi ad hoc connection between the iPad and the computer.
On the Launch page, the clips locations do not appear, but when I touch a “ghost“ location it triggers the right clip in Live. If the clip is empty i can see a short flash in Live. The others items and functions seem all there and working.
On the page Modulate, impossible to find the plug-ins which are available in the Live session, impossible to select anything and to use this page.
On the page Play, the buttons triggers the right destinations, it works well.
It works well with all the other templates i work with, e.g. Travelizer and the default Lemur templates. I only have this trouble with LiveControl_2_1_31.
I have tried to use my iPad with another computer ; on this computer, Live, Lemur Daemon, and LiveControl are the same versions and settings as on mine ; but the OS is 10.10 (Yosemite). It works well, I can see clips in the Launch page… that is very strange !
My actual setup is :
OS 10.9.5 / iOS 8.3 / Live 9.1.8 / LemurApp 5.2.2 / Lemur Daemon 5.2.2
Lemur Editor 5.2.2 / LiveControl_2_1_31 (I have followed the Liine LiveControl instructions to set it up)
Before I moved to Mavericks, my OS was 10.7.5 and it was working well with LemurApp 5.2.2, Lemur Daemon 4.1, Live 9.1.7.
Could it be a simple incompatibility with Mavericks ?!!

I have spent hours to try to fix and understand that issue without success.
Can you help me ?
Best regards

Olivier
