Changes to text using the align elements by edge tool won't save.

Hi all,

When using the "Align elements by Edge" tool to align multiple text items along a line, when I save and close the file and open it again, all the changes to the text using that tool revert back to the original position.

I'm new to microstation, is there something to do with the levels that is preventing me from making this change? The file is an existing drawing that I'm trying to update.

Thanks in advance

Tom
