this still seems like it's switching to a Tablet 7" varient before a Mobi sized

but .. maybe since you are using alot of text
here's what "Egg" posted regarding "Normalizing Text across vareints"

Select part of the text you require to amend in the mobile variant. Change it's size colour or font, then go to the dropdown menu for the text style used (Normal Text say) [It will have a + symbol after the style name] and select "Update Normal Text in this Variant". Linked text fields across variants will still have the same content but will have different styles
