Upgrading to CM Gold Doubts

Hi all, I have being using CM free version for some time now. I like it and I thought of upgrading to the Gold version but have some doubts and reservations.
I use CM for health issues and I have to take a few supplements.
I usually take the same amount of supplements like for example "Douglas Labs Vitamin D3 liquid 1000UI" on the
24th of Nov when I added the supplement CM says I took 40216UI = 6703% on the
26th Nov I enter the same amount of Vitamin D3 and the readings are 4125UI = 688%
this is just one example but I have found a few inconsistencies or bugs in the time I have been using CM, therefore I am not 100% sure to upgrade or not.
Anyone have had similar experiences in the reading of CM?
