Transferring models: confusing warning message

[SCarewe]

Hello, I am using the built-in transfer models functionality. After selecting a source master, I get this message:

"Some pairs already exist in this master.
Would you like to keep or update the values from the other master?".

What does this mean? "Keep", meaning I keep the current (target) master values? Or do I "keep" the values from the other master, and overwrite the values in the current master? Or do I keep (stop) the values from being overwritten by the other master's values?

I would suggest the following:
"Would you like to keep the values for these pairs in the current master, or overwrite them?"

Even as a native speaker, I find the ambiguity of English to be extremely annoying sometmes :)

Sorry if this message is confusing.

"Keep", meaning I keep the current (target) master values?

Yes.

Or do I "keep" the values from the other master, and overwrite the values in the current master?

No.

Or do I keep (stop) the values from being overwritten by the other master's values?

Yes.

I would suggest the following:
"Would you like to keep the values for these pairs in the current master, or overwrite them?"

Overwrite them with what? Maybe that’s still a bit unclear?

How about this?
"Some pairs already exist in the current master. Would you like to keep the values for these pairs, or use the values from [source master name]?"

That sounds good. Thank you!
