Survey with 2 handlebars fails to load in application designer

Thanks in advance for any support you can offer on this issue - its driving me crazy!

ApplicationDesigner rev. 208; Windows 10; Chrome Version 58.0.3029.110 (64-bit)

I have a draft survey of two pages, each with a different handlebar (one page as grid, the other as 1 column table). After converting the xlsx to json using the converter tool, saving to file system, refreshing the webpage, purging the database, and then attempting to preview the form, the page hangs on “loading”.

Each page of the survey previews fine when I create them individually, but after pasting them together it always fails. I’ve tried re-converting the xlsx, purging database, closing and restarting grunt but nothing seems to work. Is this an issue with my system or are surveys just not allowed to have more than one handlebar?

I attempted to attach the xlsx, two handlebars, a screenshot with developer tools and the error log, but I’m being informed new users are not allowed to add attachments. Please let me know if there are other details I can provide by way of a reply that might help illuminate the issue further.

Thanks again!
