Odd Audio Import Question

So I am importing music files (MP3) and am running into an odd situation. Sometimes the import function will work and sometimes it will not. I tried to batch import and no luck. Imported a sing file and it worked. Went back and tried to import another single oil;e no go. I have completed several project on resolve 14.5 studio and this is the first time I have run into this little gem

Thanks, Nick
