Running Multiple Models Regression and classification on nRF5340 DK

As seen in the Drive link, I merged two models to run them on the nRF5340 DK. However, while the classification model works, the regression model does not—it outputs 0. When I debug, it seems like the regression model is not being entered. Could you help me with this? How can I run both models simultaneously? https://drive.google.com/file/d/1gCtoWHGqgCz7zUKtaX2V0qn9ioP9f-Ao/view?usp=sharing
