Well, if you are satisfied with the extender's performance as it is, then just ignore the red light.
In case the connection does become patchy at some point in the future, then you can still try to find a better location (i.e. another wall socket) for the RE705X.
Anyway, TP-Link will be glad to hear that you are happy with the performance of your RE705X. 
Normally, that red LED should be linked with the signal indication for the wireless link between the router and the extender. It is enough if one of the two bands is "weak" for the LED to turn red.
Can you please double check that both are still showing "good" signal, despite the LED showing red color?
No, the message does not show because it is not part of a Mesh. More likely it's because of a weak signal.
Anyway, as per TP-Link's User Guide for the RE705X (screenshot posted previously) the red light indicates that the extender is receiving a weak signal from the router.
Since you are using the Tether app, could you please run the "Location Assistant" (accessible via the "More" menu) and check the result of this test?
If the light on the RE705X is red, then I would expect the result to be like in the right picture.
