Incorrect output of a symbolic formula

Hello. I am performing calculations using symbolic calculations. The result satisfies me. However, the final formula is output with an error. The variables following the equation refer to each other. In the image, I marked one of the examples with arrows.

The formula is correct, and when substituting values, the calculation is also correct. Only its display is incorrect.
