First, check the "View Zoom Steps" setting for your repository (in the "Manage Repositories" dialog). This option determines how many zoom levels Maemo Mapper will subtract and add when you zoom in and out (respectively). Setting it to 2 bars means that Maemo Mapper only shows the even zoom levels. It sounds like you have it set to 4. The default is 1.

Also make sure that the "Download Zoom Steps" setting is appropriate for you. Download Zoom Steps is similar to View Zoom Steps, except that it controls the zoom levels that are auto-downloaded. For example, setting Download Zoom Steps to 3 bars means that Maemo Mapper only (automatically) downloads zoom levels that are divisible by 3. Usually, you want "Download Zoom Steps" to be the same (or at least a multiple of) "View Zoom Steps". The default is 2.

Lastly, check the "Min" and "Max" Auto-Downloaded zoom levels (also set per repository in the "Manage Repositories" dialog. Those values determine the min and max zoom levels that Maemo Mapper will attempt to (automatically) download for that repository. If you have "Max" set to a value less than 20, then all the zoom levels above that "Max" will not be visible unless you manually download those maps (with the "Manage Maps" dialog). The defaults are repository-specific, but are 4 and 20 for OpenStreetMap, and the "Max" is definitely 20 for all other repositories.

Not sure how those settings could have changed themselves, but they may explain your issues.
