Plugin changes not stored

In my usual XP machine I tried to change the pdf plugin to use an older version of PDFtoText as I already did with the previous versions.
The change is operative but is not stored, so each time I close and reopen EDP the chages are lost.
I tried creating a new plugin for it instead of modifying the standard: no way. Same result.

Indeed, a bug in 15.0 Beta. Will be fixed in the next build, today or tomorrow.

Same problem again.
V. 16.0.0.5

N.B. V. 16.0.0.7 too

Yes, now it's a bug in 16 beta, the fix will be in the next build.
