Narrative:

After hearing 'flight attendants prepare for arrival and crosscheck' I attempted to disarm doors 2L and 2R; 2R disarmed properly but 2L; however; would not. After lifting the protective covering I held and pulled up on the arming lever and the vent flap handles simultaneously; but the handle/lever would not completely raise. After viewing the slide indicator; I noticed that it showed both armed and disarmed (as if the indicator was caught in the middle). I also noticed that the girt bar was neither fully clear or red and that the vent flap showed green/clear as if it were also caught in the middle. Before giving the '2L and 2R is disarmed and crossed checked' announcement; I immediately called flight attendant 1 on the interphone to inform him of the situation; I also advised him to notify the captain. After explaining the situation to the captain (via the interphone and before the opening of the passenger entry door); the captain informed me that 'the door is showing disarmed in the cockpit.' I advised him again 'the door is not completely showing disarmed back here;' at this point he advised me to 'try again;' I did and received the same results. The captain informed me again that the door was still indicating disarmed therefore it was okay to proceed with deplaning. Due to the inaccuracy of the door indicators; I requested for maintenance and was informed that the issue would be 'written up.' after the passengers had left; I asked FA1 to look at the door. My flight attendant and I then switched aircraft (to work another flight) and within 2-3 hours the in-flight office notified us of the 'live door' incident. The white door handle was never moved (at least not in my presence) therefore I still don't understand how this would've occurred; but nonetheless it happened; and these were events leading up to the incident.the manual doesn't state what should be done if this type of incident occurs; it has verbiage regarding 'live door' incidents; but flight attendants should know what they should do if the door doesn't completely disarm the first time. I am not sure if I was supposed to actually 'try it again' I don't think the captain knew if I should've 'tried it again;' I guess we were just both winging it. It's hard to make suggestions regarding 'what can be done to fix the problem' when you don't understand what caused the problem in the first place. When we landed; I properly disarmed the door; and I tried to disarm it again in the same manner when we landed (following the manual and training procedures) but unfortunately something went wrong.

Title: CRJ-700 Flight Attendant reported the 2L door would not disarm after gate arrival; so it was entered in the maintenance log and the crew left. Later the Flight Attendant was notified of a live door event by another crew; so apparently Maintenance was not notified.
