Date taken field error

[MDM]

Apologies if the following has already been noted but I've just discovered it and can't find anything in the forum about it. 

 

I'm just keywording images uploaded on Oct 28th and, instead of automatically filling in the correct date taken from the camera exif data, the date taken field is using the last modified date instead. It is only happening on this particular batch (the last I uploaded). Other images uploaded before that are getting the correct date taken as normal. I'm wondering if it is just this batch (a blip in the system around that day which has been fixed) or if it is an ongoing problem. I'm going to have the edit the images that are already on sale from this batch to give the correct dates. 

 

EDIT: Also happening on batch uploaded Oct 21st but not on previous batch uploaded Oct 13th.
