Multiply Defined between two Lib

I built a tensorflow lite micro library successfully.

In tensorflow lite micro library project

creating Library...
".\Objects\TensorflowLiteMicro.lib" - 0 Error(s), 0 Warning(s).

So, I got a .lib file.

However, something happened when I imported the library to my project and compiled the whole project.

There are multiply defined errors between the library and another library in my project . 

Compiling result In My project:

How can I remove the redefined source files btod.o? I can't find them in my Tensorflow Lite Micro library project.
