DiGi App (and MyDiGi) unintuitive graphics

[Nyaa]

The graphics for DiGi/MyDiGi can be confusing.

For viewing the internet balance/quota, the balance shows a  grey circle gradually filling up in blue  whenever I use up my Internet Quota. However, for my SMS quota, the whole circle starts out blue and presumably gradually turns grey whenever I use my SMS.

Why can't MyDiGi (and the DiGi app keeps the graphics consistent?

To make it more confusing, my app is showing that my DiGi weekend quota as "100% used" which is fine if I  used my entire quota but when I look closer, all it says is: -

5.24 MB / 5.24 MB

MONTHLY WEEKEND 15GB

So is my weekend quota 15GB or 5.24MB (which is awfully low)?
