XSL-FO customization at block in OKCTERMS_en

Hello guys, how are you doing?

I'm trying to implement a customization at contract template for purchasing module. The base file is OKCTERMS_en.

I'm trying to apply line-height at block level and also created a inline element but nothing happens... if I try another attributes it works, like applying background-color (attachment). Does anyone know what could be the issue? I'm using 200% at below example but it not work with any value.

There is any alternative that I can add more spaces between the text lines?

<!-- Here is the block with customized attributes-->  <fo:block line-height="200%" background-color="red" font-size="{$defaultFontSize}" padding-top="5pt" padding-bottom="10pt" font-family="{$defaultFont}"  font="{$font}" white-space-collapse="false" linefeed-treatment="preserve" text-align="justify" >
