Tool calling gives content response too

Hi everyone, this morning I’ve noticed that tool calling is now answering with content too, is that a normal behaviour or should I never use that pre-response?
here is an example of the output that it is giving to me:

{"role":"assistant","content":"Perfect, please wait a moment while I forward the call to a member of our staff who can assist you with your reservation. One moment please.","tool_calls":[{"id":"call_1mBv7781bpSI2rpZKIQzVZSo","type":"function","function":{"name":"forward_call","arguments":"{\"forward\":true}"}}]}

I’ve tried with other tools but it seems to not always give an output in the content field, should i still ignore that or should i use that?
