Masterpdf can not export tiff images

Hi
the flatpak version does not allows the exportation of tiff images from a pdf (files/export/pagestoimages)
however, the deb and rpm packages allow it

the manual installation command used was:
flatpak install flathub net.codeindustry.MasterPDFEditor

thank you very much

As usual that kind of problem is best reported to its issue tracker
