pb updating a content type

Hi,
On a video site, I have problems with updating elements from the font-end and only from the font-end not because from the administration, it works; this site consists of music videos and science videos; in each case there are musicians, composers, scientists, fields of science etc ...; I have a category for each when I create a video I tell it what a music video is, what is the musician, composer, style etc. a list is filled and I choose; it seems that I no longer have access to these lists (see image) and this only for music videos, everything else works; I have the same process for science videos and everything works; I did restorations, the oldest one a month ago and the same result; I changed the template and the same result; when I make a new music video creation I have access to these list but not in update .. this update has already worked then at one point it blocked ..

i think you need to check console error in your browser

i have that :
"Error: Promised response from onMessage listener went out of scope ExtensionMessagingService.js:89:34
