# Latest symbol is lost in Word equation after Professional to Linear (LaTeX) conversion

I enter the formula in the latest Word for Office 365 (version 2003 (not Word 2003, the 2020 year version), build 12624) in LaTeX mode:

\frac{x}{y}=\alpha


It converts to Professional look normally, but if I switch again to Linear and back to Professional, the alpha symbol is lost. Sometimes it is lost just after entering and the first conversion.

If it is \alpha^2 everything is OK. I can put just ^ at the end without a number, but it looks like an unfinished equation.

Does any other workaround exist to prevent missing symbols in equations?
