@__kirakira123__: That confirms my thoughts. The log shows that you've exchanged within a second 3 times 600 seed bonus points (and got the upload credit).
If you look to the left panel to your forum posts, you'll see a negative seed bonus amount "--1071.375", means since the exchange, assuming 603 balance before, about 130 points were added. However negative balances are displayed in all locations except the form side panel as zero points and you can't see that movement.
As reference here the log extract:

2015-07-16 00:00:20 System Download-Rights taken due to Low Ratio
That can happen if the exchange button is clicked faster than the system can write the change to the data base, but the writing queue will be executed a little later.
