Unable to auto detect NEJE MAX 4 device

I previously had NEJE MAX 3 and now I got NEJE MAX 4. When I try to create a new device in LB, it does not find it. I noted that If I connect using the old MAX 3, I can talk to MAX 4. I can move the laser. I created a new device manually for the MAX 4 with the correct dimension and this partially works. I have good control for the laser to cut files but when comes to engraving, the results are not consistent related to power and speed. I must be missing specific driver config file for the MAX 4. Questions: Why can’t I discover my MAX 4 automatically and is there a driver for MAX 4 I can upload in LB. GRBL 7.8.0. PS, NEJE app does recognises MAX 4 and yes I do ensure to set the Driver back to GRBL when I quit NEJE apps.

Can someone verify my settings and let me know what needs to be changed. Tks
