Blood Angel - Assault Squad Bugs

[Rumplemaster]

Hi, hopefully this is the correct place to ask this question? Using the latest download for 40K, when I select a Blood Angel assault squad and replace a bolt pistol for a different weapon the points values jump to the wrong value.

For instance:

A flamer should be 5 points but changes to 23.
A meltagun should be 10 points but changes to 28.
A plasmagun should be 15 points but changes to 33.

Hopefully someone can tell me where I'm going wrong here?

Thank you,
