Unable to switch to alternative title names in some cases

[Fonz1e]

I've noticed this issue today.
Most post titles is switching to their alternative names with bulk rename option without problems.
Unfortunatly some posts with titles begining with symbols like ❤ and _ as first title are not switching to their alternatives with bulk rename option and they are downloaded to one folder with those symbols as name.
in manual mode i can choose correct name from the list for already downloaded post and files are getting separated to correctly named folders without problems but in page containing more than 100 posts with this issue it's hard to correct all titles manually .

Same here. Frequently posts just put the collection name. Bulk renaming is impossible.
