Ekaterina for G8 should not have an issue with eyelashes. There must be something else causing the issue. If you load just the character and select her G8 eyelashes in the Scene tab then click on the three line button (AKA the hamburger button) select preference and show hidden properties, then select Currently Used, you should just have 5 properties with Ekaterina Lashes and Head as hidden ones, they should both be 100%, if the head is not the lashes will move.
Please note that this hidden headmorph is not the same as the Character Ekaterina Head morph.
If that looks okay then try this, with Ekaterina selected in the Scene tab, use the Joint editor (Alt+Shift+J in windows) to display the model bones. It should look like this

Then if you select the eyelashes it should look like this

If either of these are wrong, first look for a morph that is interfering, then try this; right click in the viewport select Edit and then Adjust Rigging to Shape.
Now all of this is a guess on my part since as you can see from my images, I do not have the same issue with Ekaterina lashes. My personal opinion is that there is another morph messing with the position.
