Thanks,
I figured this one out - it is due to the fact that the taste notes appear on two different tabs (Notes and Fermentation) - so when you delete the notes from one it changes the copy in memory but then when you press OK it grabs the old notes from the other tab.
I think I'll need to do a quick patch to fix this so when an item changes on one tab it is automatically pushed out and written to the other tabs. Thanks for catching this - it is an important one to fix, and I'll have build 54 out shortly to fix it.
