I recently updated to 3.4.2 and now, when searching for a specific set of cards to edit, selecting and editing these cards using the Edit Multi-selection function, all cards in the class are updated instead of the specific selected cards. It seems to behave the same way if I use the Select all items box or manually select the individual cards. The pop-up message confirms I am only editing the selected number if records, but looking at all cards show changes to all records.
I have dug through logs searching for any indication of what is happening, but I am at a loss to find a relevant entry for these events.
