Honestly, I am not sure what to tell you. What file format are you using here? You can always post a bug report on the Bio-Formats page.
On that page - they say before you report ... "If you think you have found a bug in Bio-Formats, the first thing to do is update your version of Bio-Formats to the latest version to check if the problem has already been addressed. The Fiji updater will automatically do this for you, while in ImageJ you can select Plugins ‣ Bio-Formats ‣ Update Bio-Formats Plugins." The newest version - 5.5.2 - was just released (see this forum post). There is also a list of "Common Issues" - just read the whole page and you'll see how best to proceed.
Sorry - that's all I can do to help in this at the moment...
