Cells not update (Version 3.6.1.2)

Cells contain formulas below:

=COUNTA(A1:A5)
=COUNTIF(A1:A5,"a")

But when I press F2 in the cell and type space to edit it and press Enter, it updates (once).

ps. No problem with others formulas.

Hi @Panya,

You mention that the cells update once when you press the Enter key. What behavior are you expecting?
