Is the Windows text size increased on the club computer? That would explain the strange behavior. In the current and previous versions of the software, the space allotted for a table is computed based on font size. If you increase Windows text size, the TD still thinks the font size is a specific height, but it is actually larger, and thus each table will take up more pixels in height. The TD doesn't allocate enough vertical pixels, so the tables overlap.
The next version has been overhauled to allow for different font sizes, so this won't be an issue whether you increase the Windows text size or use the TD app to choose a different font size. But there's really no workaround in the current and previous versions, except to reduce the Windows text size back to 100%.
