Next time, please ask on the wiki forum when you aren't sure how to proceed.
I just marked the English page for translation. This effectively removes all French content from the /fr page. It will have to be tediously added back by opening the older revision in a separate window, and doing a lot of copy & paste from the old page to the current translation, because the translation system separates the page into small translation units for each block of text separated by empty lines.
(I explained the translation process in this French video on Youtube: https://youtu.be/oXjqi6A-cb8)
Another comment: your screenshots are huge, and all with a French UI. It is best to add images that do not show the UI as most users don't understand French.
