2 months ago I was about to report this issue myself. (Note to self: Before wasting an hour gathering screen shots/assets for a new Report, check first to see if someone else has reported the issue .)
I spent a few hours doing comparisons between my custom Printer preset (which gives this bug) and the vanilla Ender 3 v2 Printer preset supplied by Orca, which works.
I isolated the problem to "Machine start G-code." (This is when G-code flavor is set to Klipper. If set to Marlin, the initial layer temp displays correctly.)
As a first matter, if you don't have any start G-code, then you will get this bug.
As a minimum, you need to have
M104 S[nozzle_temperature_initial_layer] ; set final nozzle temp
in the Machine start G-code for the display to show a non-zero initial layer temp. (Even though your START_PRINT Macro sets the first layer nozzle temperature by passing the same variable to your Macro.)
Is there an existing issue for this problem?

Anything else?
Reviewing the G-code, Orca correctly calls the print_start macro with the first layer temperatures (the printer, if the macro has been modified to use those parameters, will correctly set the temperature.) However, as the g codes are not inserted directly, Orca preview interprets them as 0degs until the second layer when the M104, M140 commands are called.
