Substitution showing up wrong in Preview

[Eusorph]

When making a substitution (deletion+addition) and going to "Preview accepting all", Commentator shows the deletion instead of the addition. When I then go and "Accept all suggestion" text comes out right with the deletion deleted and the addition showing up.

Example:
Una forza mostruosa si sollevò dentro {~~di lui ~>M04 ~~}e si riversò fuori con lingue azzurrine.
Preview accepting all: Una forza mostruosa si sollevò dentro di lui e si riversò fuori con lingue azzurrine. (wrong)
Text after accepting al suggestions: Una forza mostruosa si sollevò dentro M04 e si riversò fuori con lingue azzurrine. (right)

Many thanks for the bug reports, it seems like there also some issues with preview mode when it is combined with source mode.

I will try to tackle theses issues as soon as I have some time (though it will take a while, sadly)
