did you mean:
a) Single file from Edit mode by - Share icon/Export original/Save to Files/Drive/.... Save
Note: This is only one possible feature of Export in Lr, but there is no option select more than single (just edited) file. Then you can Export just the original file.
b) Single file from Edit mode by - Share icon/Save to Files/Drive/.... Save
Note: This is Save of edited job (file), again for one file (there isn’t select files feature)
c) selected photos from Album by - Select (photos) + Share/Save to Files/Drive/... Save
Q: is this the problematic feature mentioned by you?
