To arm a Take lane for recording Click the Take lane’s Arm for Recording button

.
You can only arm one Take lane at a time.
Note: If a track’s Take lanes are expanded while recording into the parent track, the recorded data will be moved to a new Take lane after recording is stopped. To loop record multiple takes into separate Take lanes
1.
Go to Edit > Preferences > Project - Record, or right-click the Record button to access recording settings.
2.
Under the Recording Mode options, choose Sound on Sound (Blend).
3.
Under Loop Recording, choose Store Takes in a Single Track, and click OK.
4.
Click the target track’s Expand/collapse Take Lanes button

so Take lanes are visible.
5.
Click the parent track’s Arm for Recording button. Note: It is important that you arm the parent track, not an existing Take lane.
6.
Set your loop boundaries and start recording multiple passes through the looped area. 7.
Stop recording. I took this off of the online help page. (Whats New / take lanes)
It seems what you are seeing is normal with take lanes.
