Missing some translations

I can’t get it to find several translations in my template (although it finds some others). For example:

```html

Your card will be charged { total } + VAT every month.

Your card will be charged { coupon_total } + VAT for the first month and then { subscription_amount } + VAT every month.

Your card will be charged { coupon_total } + VAT every month for the first { coupon_duration_in_months } months, and then { subscription_amount } + VAT every month.

Your card will be charged { amount } + VAT every month.

None of the above are found. However, I can match them just fine if I paste the `HtmlDirective` regex on regex101.com. So the regex works.

Any idea why it would skip them?
