Hide formulas and lotus script

I am using the ‘Replace Design’ function and ticking the ‘Hide Formulas and Lotus Script’ option to try and replace the design of my database and hide the design but I’m getting some very odd results.

Some design elements are removed from the database but still exist in the template. Elements cannot be updated (even tho the ‘Prohibit Design refresh …’ is NOT ticked and never has been.

HOWEVER if I do the same process but do not select ‘Hide Formulas and Lotus Script’ the replace works exactley as I expect it to - WHY is it different when the design is being hidden??? my head is hurting…
