I am now in 2miners and v1.37 and this is how it looks like:

The third column is estimated stale shares.
2miners pay for level 1 stales so it shouldn't be a problem. you have 100% accepted shares in the window. You can check in the pool statistics for stale shares.
This is from 2miners website, it is on the "shares" tab:
Recorded shares in the recent 6 hours are displayed in the table above. If you have a significant amount of invalid shares, please check the GPU overclocking settings of your mining rig. If there are many stale shares (more than 5% of all shares), there is an issue with your internet connection. We recommend you to ping the pool with a special stratum-ping tool. When rewards are distributed according to the PPLNS scheme invalid and stale shares are not credited.
