'Simple' Timer circuit.

Am trying to use a wireless remote trigger on a relay circuit that will turn an LED light on for 3 seconds and then shut it off until the remote is pressed again. Got the parts from Temu and very little intelligible documentation. The only time the light comes on for the set time is when I use mode 3.2 which starts the light as soon as power is applied. Modes seem to be P1 : trigger signal, relay on for 'OP' time and then disconnects. (this mode doesn't show up in the sequence of modes - starts at P1.1)

P1.1 signal is triggered again, invalid
P1.2 signal is triggered again, the clock is reset
P1.3 signal triggered again, relay off, stop the clock
P2 trigger signal, the relay is off "CL" of time, relay is On for "OP" time, then disconnect relay
P3.1 trigger signal, relay is turned on after the "OP" time, then the Operation cycle, if the trigger signal period, the relay off, stop the clock, the number of cycles ("LOP") can be set
P3.2 without triggering signal, the relay is on for "OP" time, off for "CL" time and has been cycling; frequency ("LOP") cycle can be set
P4 Signal holding function. If there is a trigger signal, timing is cleared, the relay remains on. When the signal disappears, after the "OP" time,, the relay is (???). If another signal during timing, timing is cleared
(Sorry - trying to accurately portray the codes)

I've attached a photo, if that is any help.
