Hi @Andrew Tunnicliffe ,
Thanks for your detail message of the issue.
Could please help to run the report in other browser to see if the issue will occur or not?
I tested it in my machine with SSRS 2017, things work fine.
You may download the report rdl from web portal and open it in notepad to check if there is expression you set or not .
Please also try to create placeholder over text and then setting it to render HTML.
Noticed that SSRS2017 has a newest release 14.0.600.1669, if possible, you may upgrade to the newest release.
Regards,
Zoe
