SQLite Database - Files are not updating correctly in table , which has been previously downloaded through NSURLSession Download Task

I am using NSURLSession to Download multiple files and update in database. download s happening correct for all files and database is updating properly. When i delete item from local as well database, it is deleting properly.

But, when i download new file from list, which contains part_id and Filename and click on download, at that time the part_id is not of current file. it is of last file part_id, which i deleted just before new download.

Original filename and part id before deleting any file locally and Database

1. FileName - Body Part ID - 2001

2. FileName - Break Part ID - 2501

3. FileName - Ignition Part ID - 6501

I selected- Automission Transmission file, its Part ID is 1011 but in Database it is updating with Part ID of Ignition System, which is 6501

Video Url is updating correct of Automission Transmission

Code for removing file -

NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSLog(@"Database Path : %@",VideoPath);
NSLog(@"file name : %@", fileName);

NSError *error;
BOOL success = [fileManager removeItemAtPath:VideoPath error:&error];

if (success)
{
    NSLog(@"\n Part ID :%@",part_id);
