Hiding containers in invoice customization


I have created some appended text in the invoice customization, I would like to however be able to remove or hide this text on my main invoice design and have it showing for my second invoice design which am using as a hire agreement. I have the following container in the editor which should hide the relevant text but it hides the terms container instead, which there is a separate container for.

The two containers are:

.invoice-append-region {
.invoice-terms-container {

Both of these hide the terms text which is either input when editing the invoice or setup as default text. I want to be able to hide the appended text.

Many Thanks

How exactly did you do this? Did you enter this text in invoice notes or payment terms?
