new release cause bugs on detail description

[chanifalfath]

Hi mate, thanks for this plugin.

I've been used this plugin for a while, and just updates to the latest release last night.
I found some bugs with this new release - there is no number showed on detail item of Invoice. Like on qty, unit price, discount, tax, amount. For item description, subtotal, total and other all good.

Other than that, i think all good - can you take a look on this.
I attach screenshot here.
