Images are sometimes duplicating drafts

I noticed a bug after my last trip. When you add an image to the draft and submit the draft (auto), it seems to be fine in GCDroid, like here:

Every cache seems to be counted once, everything is fine.

But when you go into the drafts on the website there is a duplicate:
I use an addon called GC Little Helper II which shows duplicates in red.

When going into the drafts of "Skarby Lasu 080", one draft looks like this:

The other one like this:

So what is happening, GCDroid uploads two drafts - one with the photo, and one without the photo. In some cases, there are more than two drafts for the same cache, and only one of them contains the photo uploaded through the app:

Probable cause:

During this geo-trip, I was deep in the forest, and sometimes there was no cellular reception. This probably caused errors while uploading photos, and when an error happened, the app pushed an empty draft, and then tried again the whole process. I've not known about this till I got home - there was no information inside the app - and to be honest, I understand that because it's some background process.

I hope you can fix that, cause this is doing some mess. I guess one of the options would be to disable auto-upload of drafts to geocaching.com and upload them manually later on when you have good internet access, but that's only a workaround, not a solution.

EDIT: I found a duplicate case, wherein both of the drafts there was the same photo uploaded

EDIT2: I also see a duplicate case when in one draft there are 2 photos and in the other one all 4 photos I wanted to add.
