Error with blynk eventor, when choose the Time trigger

Hi,
I use the local server.
I met the error like the image, so I can not set the time to trigger blynk hardware.

I dont know if this problem relate with buffer size. Because in my server, have many account with a lot of timer trigger.

Are you running latest Server, Library and App versions?

Yes, I use the lastest blynk server and android app.
