I reviewed your design and spoke to our Maestro Label Designer technical team. Unfortunately, we do not have a way to easily fix this issue. The technology that we use in Maestro Label Designer tends to have problems with the spacing / kerning between letters on some fonts when the font size gets below 8 point. Unfortunately, this issue seems to be impacting both these fonts.
We are working on a new version of Maestro Label Designer that will likely improve performance in this situation, but the new version of Maestro Label Designer that is going to take advantage of this technology won't be released until sometime in the middle of 2015.
In the meantime, there may be a few workarounds that will work. Assuming you can't use a different font, you may want to consider creating the font at a larger size and then doing a screen shot of the text at that size (you could also do the screenshot in a program like Microsoft Word). Once you have taken a screenshot, you can upload the text as an image. This obviously adds some additional time to the process of making the labels.
Here is a tutorial on taking screenshots in Windows.

I apologize that we don't yet have a good fix in place. Thanks for your patience.
