Title(object) is NA

[sabcarp]

Hello,

I used to explore pubmed thanks to RISmed for one year. And recently, I have been facing problems with the Title function. The Title(object) returns a vector containing only NA values.

Here my session info:
R version 4.0.3 (2020-10-10)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows 8.1 x64 (build 9600)
and RISmed version 2.3.0
