I recently updated LRTimpalse and also Lightroom however watching your tutorial I noticed that the new Masks were named LR1 through to 5 however when I launch Lightroom the Masks are all named the same Mask 1 through to 9 See attachments. Any help on this would be appreciated.

In the video I explain, that the preferred way to do the migration is to set LRTimelapse to use Masks 2 (in the settings) - then load any older sequence first into LRTimelapse, then save. This will migrate and also create the names. If you then load metadata in lightroom you'll get the correctly named gradients.
If you don't do that (explained as option 2 in the tutorial), and load the sequence first into Lightroom, then LR will do the migration and you'll get the wrong names. Both works, but I'd prefer to use option one as I also said in the video.
You might want to watch it again... :-)

Im not that computer savvy lol what do you mean by "load previous Sequences" Ill watch the video again and do it step by step.

Ok, my bad I should slow down and follow instructions. Thank you for the help.
