Replacing periods automatically when I use Translating Replicants function?

We use Passolo 2016.

When I say "Yes" in the Translating Replicants dialog to apply the same translation for the other identical strings in the project, it seems that Passolo replaces Japanese periods (。) with English periods (.) automatically. I thought maybe this is some Auto Correct function, but I did not find any Auto Correct function in Passolo. Is this a bug?

Thanks and regards,
