BUG: Disappearing indicator levels

[Forex Trader]

I've got a CCI indicator that I place a -144, 0 and 144 level on. Running it on 4 different pairs I've noticed that often one of these would disappear after a restart.

It turns out that unless the levels are in an order of 0, -144, 144 they are somehow not retained after a restart and one of them reverts to a 0.
