Detailed steps to reproduce the issue encountered:

Load C&D into aircraft. Power on the aircraft and allow the displays to complete self-test. Display the A/C Data on right captain’s display. Enter 1590.5 LBS of fuel in each tank via the W&B sheet. Note the FOB values on both the A/C Data and central display do not match and all display a different value (red circles on screenshot). Enter the Weight section of the FMC, enter a Reserve value of 789 LBS. Note the Reserve value on the A/C Data display doesn’t match that of the Reserve entered in the FMC (blue circles on screenshot).

Provide extra information to complete the original description of the issue:

Upon further examination, it appears that the Reserve displayed on the A/C Data page is the value in the EFB listed as “Contingency Fuel” rather than “Reserve Fuel”.

Again, however, the value entered in the FMC is the Reserve Value (here a value of 822 LBS.).

yes

Provide extra information to complete the original description of the issue:

there are also always discrepancies between the values in the Flightplan tab of the EFB which you import from Simbrief and the FOB in the center display. The Aircraft tab of the EFB where younload the aircraft also shows different values than the plane itself, and what you enter there is not saved correctly, it feels very sketchy.

Same thing here.
