Thanks for reporting this. I think there's been a change in the way that sequence operators count on the Y Axis. The bottom row is now included in the count whereas before it was incorrectly ignored. Unfortunately it means these styles need to be amended to reflect the changes.
You can fix this quite easily by opening the style editor and finding the Sequence
operators connected to the Default, Left and Right inputs. Increase the counter to 2
for the first input and the problem should disappear.
If you need me to send you and ammended version of the files please let me know, otherwise we'll fix this asap and add it to the next update.
