Problem with import content from translation

[grapix]

Describe the bug
When you have more than one translation for a post, the content import function is only working for the last language. The metabox shows all translation buttons, but on click the thickbox contains nothing. By clicking on the last button, the thickbox is filled with content/options.

To Reproduce
Steps to reproduce the behavior:

1. Install fresh Wordpress Multisite
2. Setup two more sites
3. Install MSLS 2.3.0
4. "Activate the content import functionality" under settings for one or all sites
5. Open/create a page in one of your three blogs and connect it with translations
6. The metabox "Import content" should show two buttons – click the first

Expected behaviour
The thickbox should always contain options for duplicating content.
