Dynamic content issue in Mautic 4.x

Your software
My Mautic version is: Mautic 4.x
My PHP version is:7.4.33
My Database type and version is:5.7.44 Mysql

We created an email with dynamic content blocks, but got received the email content like below

"Hello World!

{dynamiccontent=“dynamic_content_3”}

{dynamiccontent=“dynamic_content_2”}"




Can we use “Mautic Advanced Templates Bundle” feature to use the custom object field value in any logical conditions like { if xyz_custom_object.themeid ==‘535’}

Thanks in advance!!!
