I just started adding Jira Card to my newly created Miro Story Map Board.

I was successfully able to add some Story cards but its refusing to add a couple specific cards to the story. 

So this is what is happening

1. I click on Jira icon on the toolbar
2. In the Modal, I search for the issue I want to add as a Jira card in the board
3. I select that Issue and Click on Add Button

Instead of that Story showing up as a Jira card, it shows up momentarily on the board and then disappears. No error message is displayed. 

Its happening with 2 specific stories at the moment, but am able to add other stories. 
I tried looking if specific values in certain fields may be contributing to it, but I have not been able to figure it out. 

I was soo excited about this feature.. Please help!
