Remove information Matrix coefficients : BT.709

[murriato]

Hello Mr. Selur, good afternoon, first of all, I would like to apologize because I am from Spain, I do not speak English, I am translating the text with Google.
I have a template to make 1080p x265 encodes and for now everything is perfect but for a few days I have been getting information in the media info that I do not understand and I don't know why I am getting it.

Language                                : Spanish
Default                                  : Yes
Forced                                  : Yes
colour_range_Original                    : Limited
Color primaries                          : BT.2020
Transfer characteristics                : PQ
Matrix coefficients                      : BT.709
matrix_coefficients_Original            : BT.2020 non-constant
Mastering display color primaries        : BT.2020
Mastering display luminance              : min: 0.0050 cd/m2, max: 1000 cd/m2

I wanted to ask you how I can remove that information from the encode?

In all the previous encodes I did not get Matrix coefficients: BT.709
