Unable to trigger onTap event on first sticky header

Hi, first of all thank you for this plugin. I really love it.

There is one thing I can't seem to figure out, which is why my first sticky header is not able to register any onTap events. Other sticky header is okay.

If you look at the image below, imagine a container surrounding the "xcodes and #1". The icon on the right, upon onTap it will open a pop up dialog. I tried clicking on it many times but it just wont trigger the onTap event, only for the first sticky header.

Managed to trigger onTap event when i aligned the dotted icons at the bottom. Not sure why though, im pretty sure the layout above it is not overlapped
