Strange spacing on - character

Hi Fontself community,

When I type - and the hit space, the size of the space jumps massively. Then if I type after this, the - moves further to the left with each character. Below is an example of what this looks like.

I used the smart spacing, which worked great apart from this strange anomaly.

Does anyone have any idea what the solution would be?
