TYPO3 Core

I have 4 content elements all together, 2 in english and a translation of those in german.
English is the main language and i am in the Language view at a page where you see the languages side by side.

when i move the first ce of english down, only this content element is moving down. ok, now i move the first german ce down which is the translaton to the one that we just moved down. we see a cross of the content elements now.

now let's move the first german ce also down that we have all translations at the same "level" again. so far so good, i can move the german ce up and down and nothing changes but when i have the german ce at the bottom and moving the ENGLISCH one up again, BOTH content elements are moving up (the english one and the german translation to it).

this is very strange.

ok, this was in live workspace. now let's change to workspace view.

when i move the first english ce down, i suddenly see the german translation in the english column. what? after publishing the changes in the versioning module, both ce's are in its own column again (somehow i have 2 items to publish, the german and the english).

i don't know what SHOULD be the way it should be (moving only one ce at a time or both together) but one of those wrong behaviors shold be fixed.

i hope i could describe the situation so that it is understandable, if not, please ask.
