This is an update....

the plugin has issues beside those specified. have loaded a list with 1800 ads (behaves the same with 2 ads), after the initial load, prior of actual import, page behaves very slow. no problem in the end becouse the ads are loaded (all 1800 wich is great).

main problem is that half of the fields from the list are not loaded, 1 is loaded wrong - if no value is inserted in the box, the field does not show when i add it manualy. in this addon, i have such fields showing with 1 as value when they should not show at all becouse in list there is no value set -blank area.

another issue is the text format in description wich in the list is ok, in the actual add it shows ok (in frontend) but when i try to edit it, all the lines forms now a huge line and that will be save in the end unless i start spliting the lines again...
have raidsed a ticked with all details - UEK-189532
