Just to be on the safe side - you can & did unlock the wallet, right?
I would expect it should work that way, sorry to hear you're out of luck for now! I haven't tried this myself, tbh, so not sure if there's something that you missed that is different, or if there are some additional steps you may have to take to get it working again.
At this stage there are many questions in the UI. There is no way to tell what your being change for and why.
Regarding the post however- I think your funds are spent and have you hog tied because you sent some in- but it wasnt enough.. and those coins are immediately spent.
So something we have learned here is - do not make an allocation that you do not have. I would be curious to know that if you bought more coins would those auto deduct until you paid the full 5000 SC.
In my case I had the 5000 SC and it took them out immediately for holding. Now if I do not use any of those a portion are suppose to come back after 3 months. But again.. this is in theory. Long story short is- unless you have enough SC to tie up for 3 months do not do this. May need to wait until the UI becomes a bit more robust.
After 3 months I will be able to report back on the SC I used for allowance.
