Text tags Initials align right

Hi,

I am using text tags to build our agreements to use in Salesforce. To include initials on each page I use the text tag: {{*Init_es_:signer1:initials}}

But by default everything is aligned left. I found settings to customize tags alignments:

:align(left) – Aligns the text in the field to the left. This is the default behavior for form fields and the directive does not need to be satisfied.

:align(right) – Aligns the data in the field to the right.

:align(center) – Center aligns the data entered in the form field.

I used :align(right) but before signature it seem to be fine but when signin it's going back tp left.

Here is my tag: {{*Init_es_:signer1:initials:align(right)}}

When previewing the document before validation: (paraphe is initials in French)

And when signing:

May I missing something?

Thanks for the help
