Functions of the Add-on not stop
I would like to install your plugin to my real site but I have find a big problem.
The functions of the 3 add-ons not stop: Premium, Bump up, and VIP add-ons.
The ad have started 04/10/2019 with TOP ad package (duration: 20 days). TOP ad package include your default Premium add-on. The ad owner upgrade his ad with a Bump up add-on at 04/12/2019. Bump ad add-on valid until 7 days (04/12/2019-04/19/2019) but your plugin bump the ad for 04/30/2019 (until TOP ad package's end), not stop at 04/19/2019. The CSS part of Bump ad add-on stop but the bump function not stop.
This problem is at every 3 default add-ons. (The post-order Premium add-on list the ad at TOP of listing until the end of the package's validity, the post-order Bump ad add-on bump the ad until the end of the package's validity, etc.)
