I am using GPE calendar and since upgrading, cannot enter appointments at 11:xx or 12:xx anymore, as the last digit entered in the hour-field is automatically followed by a space. Not an issue with hours 00 through 09 because the calendar accepts a single digit and a space as valid input as well. 11 and 12 can also be entered by clicking on the clock symbol & scrolling through the hours, so it may seem a small nuisance, but it makes the GPE calendar unusable for my purposes.

The corresponding option (I guess) in Settings -> Text Input -> Insert space after word is not activated and never has been (tried switching it on, on and then off, but no difference).

I'd really appreciate it if someone knows a workaround for this.

I would also like to know what to expect when restoring the backup made before upgrading.
