Wav file Insert Synth

Having some issues inserting a wav file downloaded from a 3^rd party software,
 ‘Loop Loft  MiniDemoPack_WAV’ to be exact, into my EZ Drummer 1. I am considering the purchase of some brush loops from them, in a .wav format.
 
The .wav file plays in windows and in my Loop Explorer preview, but when I ‘drag n drop’ into my inserted synth for EZD, it makes an Audio file by the same name as the .wav file, and only puts a “dot” in the middle of each measure. There is no audio heard as I try and play the file.
I have tried some other samples from ‘Big Fish Audio’ and they work fine.
 
Does the wav file need to be an wav-acid file ? The wav file from both of the 3^rd parties seem to be the same in windows as far as the extension is concerned.
Is there a special way to insert .wav files ?
 
All help/comments appreciated.

EZDrummer only uses Toontrack EZX expansion packs for added sounds. There are 3rd party MIDI loops for EZDrummer but no audio loops.
 
When inserted audio files cause dots to appear in an audio track it means the audio has been inserted far to the right. This shift to the right is the result of special handling of broadcast wave files. Broadcast waves contain a timestamp which the DAW uses to position the clip. Cakewalk provides a preference setting "Always Import Broadcast Waves Their Timestamp" which is defaulted on. When this preference is set off, the timestamp in the broadcast wave is ignored and the file can be imported anywhere on the time line.
