Charm Pack not square

[Liberty]

I've never had that problem with Moda. I buy charm packs (and use them!) all the time. The only problem I've ever had was one had very obvious selvedge.

but even that was square at the same size as the rest.

I've never mixed and matched brands when I use charm packs, so the small difference in 5" interpretation doesn't really affect me. But I will think twice about buying Bernatex!
