I have some modifications in my template and after upload it the default template is back to default, and all I do the modification I find that it automatically changed to the default value

example I need to change in (tcreative template CSS)

sp-footer #sp-footer2 { text-align: right; }

to

sp-footer #sp-footer2 { text-align: center; }

After refreshing the home page, the values will return to what they were by default.

I've made all my attempts, but unfortunately, they all failed.

Any suggestions?
