Cannot buy the last share

As CEO. I am trying to 100% acquire the corporation TG Eldon Factory MUs on LU. According to the list of share holders, I own 100% (28,812,495 shares). However, when clicking on the 'buy shares' option, I see the message that we have already asked for 100% of the shares and there is a demand for one share outstanding - yet this share does not appear to have an owner or, indeed, exist.

How does this get resolved please?

Well, it seems to have resolved itself as it is now wholly owned as a corp. But still a strange message.

could be a rounding off issue.
possibly a bug with large numbers and 1 share missing.

if it happens again, please let me know, plus all the data to be able to look into it.
