Added Bulk Test cases were not displayed in the list all the time until we refresh the page.

I found a bug in the test cases section. Is it a bug for others in the community or Only me? 

I am a tester and just started learning Zephyr and found this bug:

Adding a test cases was going smooth as expected. And when you add bulk test cases then it also goes smooth. But when you open any test case and came back to test cases library then those new bulk test cases are not displayed in the list. I refreshed the screen then it appeared back. 

So I tested same again and again, it is happening same every single time that test cases are missing until refresh.

My Observations: 

In this  first picture, I have added t3, t4, t5 as bulk then I did one clone t6. then I opened a test case and came back to library.

In the second picture, thats the actual result. 

Now, Until I refresh the screen it does not display those added bulk test cases. Then repeat the same actions (open any test case and come back to library and observed same).
