possible reasons:

Too low a temperature for the size of the mould.

Too short a soak (i.e. none) at the top temperature.

Your top temperature is at the low end of slumping temperatures, so you need a long soak.  The smaller the mould, the greater the time it takes for the glass to slump – weight and gravity apply.  As I don’t know the size of the mould or its shape, nor the size or configuration of your kiln, I can’t really be more specific.

I do have a range of suggestions in my blog, though. use “slumping” for the tag.
