Unable to raise an alert

Today I raised and alert for EA2/NV-151 tomorrow at 7:00 utc for the VK-ZL <> EU S2S event without any problems, but right after this one I tried to raise a second alert for EA2/NV-119 at 1045 and it doesn’t get displayed on Sotawatch.
I raised the first successfull one from my smartphone and so I tried for the second unsuccessful one.
I also tried different times and different summit numbers with the same result.
Now I have just tried it again a couple of times from my laptop and again the same result of alert being not displayed.
This is what I’m typing:

Can someone help me to fix this problem?

Thank you!
