Configure Panel & Monitor Settings don't really match

[guiverc]

It appears that Monitor Settings starts counting at 0

However my added PANELS get bounced around; and I want a panel on what is listed in Monitor.Settings as HDMI-3 requires me to selection position as Left.of.Desktop.4

I suspect Monitor.Settings starts counting at 0; where lxqt-panel starts at 1.

NOTE: this is not a serious issue, but petty, being an inconsistency (hidden between one dialog calling it monitor & the other desktop; what I've taken as being the same thing)

Expected Behavior

Given I'm reading my monitors from the Monitor.Settings where my monitors are numbered 0-3, when I select my panel to appear on the "Left of desktop 3" I'm expecting it to appear on HDMI-3 in the matching Monitor.Settings window

Current Behavior

It's drawn on the HDMI-2 monitor.

Possible Solution

My suspicion is lxqt-panel counts from 1 (first monitor), but Monitor.Settings in contrast starts counting at 0.

Steps to Reproduce (for bugs)

1. It'll require a multi-monitor setup
2. Open Monitor.Settings window; and I'm using the last DIGIT (0,1,2,3) as the Monitor Number
3. Right Click a panel & Configure.Panel.. In placement tab it's the POSITION drop-down (there displays start at 1 and go to 4 (they're 0-3 in Monitor.Settings on my box)

Context

I've not filed this bug on Launchpad or Lubuntu's site, but can if helpful.
I've not confirmed this report as on another GNU/Linux system either (sorry I guess)

I've been moving monitors around between boxes of late, and every time a new monitor is plugged in, my monitor layout gets readjusted & I'm (mentally) losing track of which monitors are which (an IDENTIFY button that display a number in monitor settings maybe nice here too; but I'm off-topic sorry).

My current approach is to re-open Monitor Settings and read the numbers shown from there, ie. this box currently has

DVI_1-0
HDMI-1
HDMI-2
HDMI-3
