How to fix blue lines on AE alpha export

[jahanzeb_dsp]

Hi All,

I am getting blue lines on alpha channel export.

I animated lower thirds and exported it on alpha channel. 
When I import it to premiere it works fine but later on if i restart premiere to make any changes it shows blue lines on that alpha channel. I have attached screenshots as well.
Please help me in fixing it. Thanks.
