Thank you for bringing this to our attention, ss_plastering. I'm here to provide troubleshooting steps to resolve this matter.

First off, may I know what Preview and Export function you're referring to? Any information you provide will assist me in delivering a more precise and tailored solution to your needs.

In the meantime, if you're referring to the Preview and Export functions when printing financial transaction forms and reports, I recommend logging into your account through a private or incognito browser to access the most recent version of a webpage without storing data that causes display issues. To do this, press the following shortcut key on your keyboard:

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox: Shift + Ctrl + P
• Microsoft Edge: Ctrl + Shift + N

Alternatively, I recommend clearing your cache to update any website preferences that might be affecting the program's functionality. Also, ensure your browser is the latest version since using an older version can lead to compatibility problems. You might also consider trying a different supported browser that is up to date.

Moreover, you can customize your reports to focus on the most relevant data, making it easier to analyze trends, identify areas of improvement, and make informed decisions.
