[BUG] On Model Load, some tracking expressions contain ?? at the end, or other characters, and not the intended expression.

• I have tested and confirmed that this is an issue in an official branded build.

Describe the bug

I am loading a model in Session with the intent to edit or modify tracking expressions.
I expect the expressions to be the same as they were when I last saved the file.
Instead, I see the text "??" at the end of expressions, and sometimes other characters. For expressions that change over time, sometimes the text also changes over time. The text that changes is not always on the parameter that changes.
When I click in the text box for the expression, the text that is displayed reverts to displaying how I'd expect it to display.

I noticed this problem when I realised my tracking changes were not saving to the model file correctly, and I found I had to click in every field to ensure it was displaying correctly before the tracking would save to file. Thus, I'm unable to tell if this problem is just related to text display in the UI or if something further is happening.

One last thing I can think of is that I am opening Session without PuppetString open so there is no blendshapes loading. I tried going through the steps again with puppetstring open and got different text inserted.

I'm going to attempt to attach some screen captures of the text.

Reproduction

The issue is repeatable every time I open this unfinished model (see attached).

This is a known problem caused by imgui's way of interpreting dlang strings.
It's planned to get addressed through the gui engine change planned to release on 0.9

Thanks grillo, I didn't realise it was the same as the previous time I reported this imgui thing (that was in creator?)
At least its in the bug list now for any future bug reporters to see.
