Onions still small

This happened last year. I grew onion sets and they came to nothing and went slimy and soft. I am looking at my Settons which were planted a couple of months ago and they are hardly any bigger than when I planted them except for the shoots which are tall. I dug around them and had a feel of the bulbs feel soft and slightly slimey.

Is this curtains again ?

Mine are the same so I wouldn't worry.  One of my onion beds, interestingly the one nearest to the chicken run, keeps getting pulled up so I have just about given up on that one.  But with the others I shall be patient.
