Well here is the odd thing. After you asked this, I started looking through the data of my past rides when I had the issue and the rides since it was fixed... and the firmware version is the same.
My Mini is 1.10.3. (227)
Speed sensor 1.2.39

So I reached back out to Brad who is the tech in charge of the issue I was having and asked him about the version numbers and to verify that I am on the latest.
He said that the developers did release a patch to fix the issue however like other software vendors, it may or may not have bumped up the version number as it was just a patch. He did verify that the versions I have above are the latest.
All I can say is I put it through its paces and I do not have the problem anymore. Is that the same version you have? And are still having the issue of deleting pages?
