File manager issues

Club 4470 - I have tried to delete obsolete PDF several times and they still remain, I have tried to unlock files, but they remain locked. Please advise?
Thanks!

What are the names of the troublesome files??

Thank you for contacting me.

BET_MONTHLY_SEPTEMBER_2013.pdf. Last night at 1am I must have deleted -saved-exited 5 times and each time it returned. At 2am I decided to give up. Today I was able to delete.

000_Current_2014_01_BET_Monthly.pdf. I tried to change properties from locked to unlock and same story.

Was there an issue going on last night that has since been resolved?.

Just now I realized I named an up loaded file called 2013_10_BET_Monthly.pdf as 2013_09_BET_Monthly.pdf. When I try to correct the name to be 10 not 09, hitting save and save and then exit. It still is wrong when I get back into file manager.

4pm PST have same problems as last night at 2am. File name 2013_09_BET_Monthlly.pdf won't delete. 2013_10_BET_Monthly.pdf - won't go public.

Correction, 2013_10_BET_Monthky.pdf won't upload....looks like a phantom file that's why I can't make it public.
