Menu doesn't stay still on first section

Hi everyone. First of all sorry for my english, i’m argentinian and i will try to explain myself properly. I’m also new on Ionic so i hope this question isn’t silly.
I’m using the side menu on my application. I have discovered that when i have many items in it and have to scroll down to see them all, the menu does not stay still when i scroll horizontally to open it. This happens only on my first section when the application starts. If i go to another section and then back to the first one, the menu stay still properly. I have this problem when testing my app on Android.
I hope someone can help me because this is driving me mad.
Thank you very much!
