Test Cycle Data in Zephyr Squad

I Created a Test Cycle with name Test Cycle 01 and mapped 20 TC in to this Test cycle 

I Executed this TC ,in which out of those 20 TC , 7 cases were fail

Now i created Test cycle 2 and mapped those 7 failed cases in here 

Noe now the concerns are mentioned below

1.for both TC i created a TC Folder, what is the actual use of those folder?

2. In both TC i am not able to find the TC mapped , TC can only be seen when we open the Execution folder, what should i do to see the TC in respective Test cycle Folder?
