Star Chart

flightsoldier

I had recently collected enough mats to raise the level of my star chat from level 37 to level 38. the star chart needed a required 185 mats to successfully level. I added the mats from various PWI Dailies. But when I did, it took the required mats and went back to level 37 instead of raising it to level 38.
Since then I still am collected the mats from the dailies. Currently I am about half way to raising to level 38 again, but I am worried it will just take the mats again and stay at level 37. any assistance on this would be very helpful. After all collecting 185 pearls to level the star chart takes some time to complete. I just don't want it to happen twice.
Thank you
