Custom supports in in cura v3.6.21

How do I place custom supports on a model in cura v3.6.21
After placing supports where required on the model, then try to resize the blocks they disappear!

Your help in this matter would be much appreciated.

I’ve never had any luck getting custom supports to work in all the versions of cura I’ve used. From what I’ve gathered it’s a weak point of Cura LE.

Thank you for response.

I thought that that there was something I was overlooking.

Maybe someone else will have a solution?
