Hello @Jenix
First of all, it’s nice to see you here. Welcome to The ants forum community. 
You don’t need to worry about this issue. Once you complete the required objective you will get the rewards.
Let me explain to you the logic of coins in general.
1. Complete daily tasks to collect Active Coins and obtain valuable rewards.
2. In each stage, there is a final reward, and when you reach the limit of the current stage’s
progress, you can unlock the rewards for the next stage.
*Special Note:
If the accumulated Active Coins for the current stage have reached the limit and the rewards for the next stage are still not available, you will not earn additional Active Coins from daily tasks during this time.
If the accumulated Active Coins for the current stage have reached the limit and the rewards for the next stage are already available, any subsequent Active Coins earned will be carried over to the rewards for the next stage.
Just getting this much time on each task on a daily basis is an excellent achievement. So you don’t have to worry
