Checklist visible but not editable on repeat tasks

Hi Aymeric

I just came across this bug today when I was setting up a series of repeating tasks - basically I have been setting up task 'slots' for the day, then per item, adding a small checklist

When I first add in the checklist items, they show up in the list - however, once saved, even though they can be seen in the column view, when I expand the view for that item, the checklist is blank.....

I can then add additional checklist items, which increase the checklist tally in the week/column view, but in expanded view, it shows as empty again.

I've added a couple of screenshots below to help explain
