Troubleshooting w Instance Slider and Vanilla

Hello I’ve followed some threads about problems w Instance Slider by @Tosche and also some other threads about Vanilla and Modules.

Both of two works oddly: If I install Vanilla and modules then I check on macro panel the print string says it is installed correctly, so I add the Instance slider script, launch it, and it works as should be.
But If I close Glyphs and restart both, instance slider and Vanilla does not work anymore.

The printout from the macro, about vanilla, after restart of Glyphs:
Traceback (most recent call last):
File “”, line 1, in
File “”, line 1, in
from vanilla.vanillaBase import VanillaBaseObject, VanillaBaseControl, VanillaError
File “”, line 4, in
from AppKit import NSFont, NSRegularControlSize, NSSmallControlSize, NSMiniControlSize,
ImportError: cannot import name NSLayoutAttributeLastBaseline

My specs are: Glyphs Version 2.6.2 (1264), on High Sierra 10.13.6 (17G8030)
