Hi Andrea,
Thank you for your advice.
How these .idm and and .ind files were created?
These files are created by reading ESRI coverage data used in an application
under ArcInfo:
vLayer = qgis.core.QgsVectorLayer(coverageSource + "|layername=arc",
layerSourceName, "ogr")
and I created shapefile like this
qgis.core.QgsVectorFileWriter.writeAsVectorFormat(vLayer, \
shapeDestination + "/" + shapeLayerName + ".shp", \
"utf-8", \
srs, \
"ESRI
Shapefile")
What is interesting not all the shapefiles have these idm and ind files.
QGIS 2.18 did not have this problem.
Anyway, I assume I can have a general script to remove any file with extension
idm and ind.
Cab these file be recreated without knowing?
Thanks,
Marian

Hi Marian,
I advise you, for the future, to avoid sending e-mail messages to a mailing
list user personal e-mail address (unless requested) and instead please always
prefer to send the message/replay to the mailing list e-mail address. Moreover,
better to avoid attach big files to an e-mail message (better to specify a link
to an online resource).
Looking at the provided ESRI Shapefile layer, it seems to me the issue is due
to the fact that in addition to the typical ESRI Shapefile files (.shp, .shx,
.dbf, .prj, ...) are also present the non standard .idm and .ind files which
contain the "attribute indexes as a mapinfo format index" [1].
If you remove such .idm and and .ind files, then the issue will not occur with
your ESRI Shapefile layer.
What I suppose is that while QGIS, using the GDAL/OGR library, can use such non
standard .idm and .ind files for attribute indexes, it (or the GDAL/OGR
library) fails to properly update such attribute indexes files when a new
feature is added to the layer. You can check this just looking at such files
modification time in you file system when a new feature is added to the layer:
such files are not modified.
Best regards.

Hi Andrea,
Thank you for your answer.
I attach the an archive with the shapefile in question.
I also attached a video to see what is going on.
