Saved Filter, add project is different from user to user

Example:
we have Projekt “PA” and a Subprojekt “SPA”
add a new “Saved Filter”

  • when user UA types “s” in the Project field.
    • a list opens with an entry “SPA”
  • when user UB types “s” in the Project field.
    • nothings happens,
  • user UB must type “%” to get the list.

So this happens when repeatedly typing the same letter twice?

Can you reproduce this on try with the new filter syntax?
