Past and present tense in a one sentence

What we understand as “love” was put into our mind in childhood when we didn’t understand that term. The way our parents treated us in childhood reflects on our subconscious and understanding of love.

I am concerned about the second sentence tenses (past and present) and its grammar.

"The way our parents treated us in childhood" is a noun clause and the subject of "reflects".

Compare:

{The way our parents treated us in childhood} reflects on our subconscious and understanding of love.

and

{It} reflects on our subconscious and understanding of love.

As a consequence, the tense of the verb in the noun clause is irrelevant to the main verb "reflects".

Compare:

{The way our children will treat us our old age} reflects on our subconscious and understanding of love.

{The way our friends treat us now} reflects on our subconscious and understanding of love.
