Can't See Campign Dates And Impressions Remain In Campaign Interfa Options

[alexfear]

Hi!
I have an issue with OpenX 2.8.8 upgraded from v2.8.7.
OpenX doesn't show information about campaign dates, rate/price, impressions configured and impressions remain in saved campaigns interface. I can see dates and impressions configured in campaign list but not inside campaign. But there is no number of impressions remain.
To see the dates i have to change campaign type and change it back, but i still can't see the impressions configured and impressions remain.

By the way: statistic is runnig well.

Img tag doesn't work, so the screenshot is here.

Thanks for help!
