Script error after changing width DG

[sphere]

Hi,

i do not understand why there suddenly is an error after changing the width of the DG and the rows and their respective fields/groups in the property inspector. (LC901 and win10).
Note that all is working ok and only the width of some items is changed.
Did not see this before.
After switching cards or saving and reloading the stack i get next errors: how do i solve it?

So i tested it on MacOs Mojave.
Same issue, but now i found what is causing it.
It's setting the 'Show vScroll" to Auto.
Reloading the card gives the error. Although, as you can see in the screen shot in the post above, the script editor itself does not show an error.
Setting it back to true removes the error.
