The merge with button doesn't show another file, while i have opened and preprocessed them both like i have done before. This time the option doesn't show, what can i do about this?
I have found that when i press the merge button on the turboprep slide, all my progress so far is thrown away, so in the merge option i have the original file back, not preprocessed. How is this possible?

Hi @rosaliebakker3,
This should obviously not happen. I would really appreciate if you could help us to figure out what exactly happened and if this is "just" a user interface problem (where we failed to explain why certain things will not work) or a serious bug. In particular, could you give more details (like screenshots, data, description of steps you did) on the following two points:
- "This time the option doesn't show" - what did you expect to show, what exactly did not show - can you share more details or screenshots please? I have some theories about this but would like to confirm.
- "so in the merge option i have the original file back, not preprocessed" - this is a complete puzzle to me to be honest. Again, can you please describe what you did exactly before you merged and how you tried to merge the data?
Many thanks for your support on this.
Best,
Ingo6
