Log Shipping Restore Job working but DB not restoring

Hi All 

I had a problem with log shipping.

The first time i setup log shipping. Restore job working fine.
But after i edit destination folder in "Copy File" Tab Menu,

before the destination folder is \\HQAPPDB\Data_backup then i changed to \\HQAPPDB\C$\Data_backup

then restore job, stop restoring secondary database, but copy job still copying all transaction file to \\HQAPPDB\C$\Data_backup

I think i cannot simply changed like that.

i changed back destination folder to  \\HQAPPDB\Data_backup, sync primary db and secondary db, then enable backup, copy and restore job

but still secondary db not restoring.

Any solution for me so i can make restore job working like the first time i setup ?

I really appreciate for your help

Thank you so much.
