As far as I remember, you always had the option of purchasing or not purchasing the Feature Set on Logos, as the image bellow indicates

However, as I checked today, it seems like this is no longer the option:

I am a LogosNow member. Why would I want to spend money on features I already own? This collection was about $88 without the Feature Set and Dynamic pricing, but today it went up to 379.16 and I can't change anything.
What is going on?
