Data structure lost

Hello, I am using four E22-900T22D, three as transmitters and one as receiver, each transmitter sends a data structure every 2 seconds:

   struct Message {
     chartype[5] = "1";
     byte amp1[5];
     byte volt1[6];
   } message;

struct Message {
     chartype[5] = "2";
     byte amp2[5];
     byte volt2[6];
   } message;

struct Message {
     chartype[5] = "3";
     byte amp3[5];
     byte volt3[6];
   } message;

The receiver receives the data from the 3 senders well, but there are times that I lose messages. I want to use the function, ResponseContainer rs = e32ttl.receiveMessageUntil(); to read each structure individually. Can I use the function, ResponseContainer rs = e32ttl.receiveMessageUntil(); to receive a structure or only be used to receive a string? Thank you.
