I am afraid I have made something of a mess out of your translation of Kdenlive/Manual/Effects And Transitions. All your translated text should be in place but the page displays nothing. I suggest we wait a couple of days to see if this is just fuzzybot playing up. I still have your original text so nothing is lost.
No need to worry. I will revise the translation by myself. Thanks anyway.
Everything is back to normal - your existing translations are back (I didn't touch your recent edits, of course). Silly mistake on my part - I simply forgot to close a brace matching comment.
