Hello jacid2000 -
We are not aware of an issue that would prevent new listings using the new templates from being visible in preview entirely, so based on your description here, it is unclear what may be occurring for you.
There is an issue that we are looking into where the preview does not show your text or profile in preview unless you have already added an image to the listing as well. There is another intermittent issue where the preview only displays a portion of the template, but this typically resolves by closing preview and then launching it again.
Both of these issues are being looked into on our end and I will update this thread as soon as more information regarding either of these issues.
If the issue you are experiencing differs from either of these, please file a support case from under the Help tab of the site that includes an example or two of where you've run into this, the exact steps you take that get you to that point as well as your browser and operating system information so we can investigate this further.
