Hello,
the most upper diagram has some wrong functionality of pool lines…
there are not visible the names given on the left sides (horizontal pools)
and there is not possible to update their overall sizes… with the edge (corner or side) black “buttons” you can manage size but nothing happens … you change only in “invisible” way and real corners (black lines) stays where they are .
about : there is not possible to update their overall sizes
by default all pools are “Auto Stretch”
you can turn off “Auto Stretch” for whole diagram via diagram popup option
