The custom filename format (.GCODE) does not work

The custom filename format for GCODE output does not work.

My expected filename format
{print_time}_{input_filename_base}.gcode

My output (regardless of the custom filename, it is always the same)
dice.stl → dice_plate_1_gcode.gcode
Yes, the format .gcode is repeated. In this latest version it no longer sets the time.
I have version V5.1.4.10249 Release.

Does this happen to anyone else?
