IOS OpenGL ES Analyzer lists "Optional Framebuffer Application" and "No Framebuffer Attachment", but FBO works

I am using an OpenGL framebuffer object (FBO) to implement stencil shadows in iOS. The code works, that is, visually the stencil buffer performs the task, and the performance seems to be excellent.

When I launch the application using the OpenGL ES Analyzer tool, it complains about the "nonexistent Framebuffer application" and the "Missing Framebuffer Attachment". I can not understand these messages, since the FBO has applications for color, depth and stencil. Calling glCheckFramebufferStatus () returns GL_FRAMEBUFFER_COMPLETE, which indicates that there are no problems.

Is this a bug in the OpenGL Analyzer tool?
