Trying to compare different models.

So I am trying to use neural networks for time series forecasting. I have created 3 different models (LSTM, CNN and a LSTM-CNN hybrid). Now I want to compare their performance based on the metrics MAE, RMSE and sMAPE. Here comes the dilemma, whenever I retrain the models on the same dataset, the performance of every model changes, and the previously best performing model now performs the worst now. I have tried to set the random seed to a constant, yet I am facing the same issue. Please help 🙁 Thanks.
