All of those listed happens to me if I try a turnourund.
The only way I´ve found to do is: If doing a turnaround:
Sett the payload into the tablet, insert the flight plan and set the MCP.
Start engine number 2 in hotel mode and than insert the payload, trim and other stuff into the computer. It works. The Confirm TO data sometimes works, sometime dont. If don´t, set PERF into the First officer side and confirm into the it´s side. It will work.
The V-FP won´t remove at all, but the other modes will work if you select. But you can´t see them. Like the V-FP is above the mode selected into the PFD but you can select IAS, VS or VPATH modes normally.
