Peculiarities with RepRap Firmware 2.01

I am trying RRF 2.01, the firmware displays:

Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 2.01beta3(RTOS) (2018-07-25b1)
WiFi Server Version: 1.21
Web Interface Version: 1.22.2

When try to “Simulate File”, Print Status shows print information, Layer Statistics etc.

When choose “Print File”, from G-Code Console:
12:19:51 PMM32 "tablet25.gcode"
File tablet25.gcode selected for printing



But Print Status doesn’t show anything.

Also, not sure what resolution the web interface is made for but @ 1400x1050 have to scroll up/down quite inconvenient. Can this be optimized ?

Did the print succeed? Were there any error message popups, or error messages on the GCode Console page?

I tried another file, yes it shows finished printing message, just some connection errors. Please see the attached images (#3 - simulation):
