Preview Invoice & Proposal didn't change - by: johnjohn

Hi,
Everyone

I have a something problem on Preview PDF on Proposal & Invoice.

After modify some bank account, name, or something else on Invoice, and than valdate it.

The Preview didn't change as i modify before (i do generated it, try delete it and generate again) but didn't change on preview.

*The modify change if i download the PDF File.

Does anyone have similiar problem, on preview Proposal or PDF?

Thank You
