I’m not sure, but it looks like beta version 1.3.17 changed the way of sorting the queue, compared to the previous versions and to the stable version 1.3.15.
If I’m not wrong, the standard behavior was having the parent card shown before its children (especially when it is a descriptor, so that both front and back side of the parent Rem are shown in the hierarchy of the children card). That was perfect, as otherwise the content of the parent Rem would be shown in the hierarchy before the parent itself was recalled, messing the active recall for it.
(E.g. This card should not be shown before “no ENC available?:: Indication” in the same section!)
Now it apperars to me that beta version is sorting randomly, many times showing the children cards before the parent card, what is not desired, as the active recall of the parent itsef (if it is due in the same section) would be compromised and messed.
If you did change it, I would ask to return to the previous behavior in this particular.
P.S. I’m not sure this problem is restricted to Beta version.
