app_timer trigger immediatly on SDK13

Question

Hi, 
 I have an issue with app_timer (nRF52, SDK13.0).
I use a single shot timer. 
I try to debug, and I'm in the case of app_timer.c line 650: 
 ticks latest: 534879, ticks at start: 12012818
ticks first interval: 163840
 
 So this case put the ticks_to_expire to 0... I don't understand why ? 
 It think that it should be: MAX_RTC_COUNTER_VAL - delta_current_start + p_timer->ticks_first_interval;
