Your model MacBook Pro can power external displays at 60Hz in the following combinations:
One display at 5120 x 2880 resolution with over a billion colors
Two displays at 3840 x 2160 resolution with over a billion colors

Apparently, the MacBook Pro can only power external displays up to 5K resolution.
What you can do to use both the monitors is:

I would recommend getting TB3 enabled monitors, then daisy chain them, less cables and easier access. "https://www.lacie.com/manuals/6big12bigtbolt3/daisy-chain-and-power-delivery/"
Here is an example of a monitor you can daisy chain with thunderbolt 2
