GTM wrong discovery of virtual server

HI everyone ,

 

not sure if this is a bug in GTM (10.2.4),

 

we have 2 LTMs per DC (assuming DC A and DC B) , i was configuring a new service and accidentally i created the VIP example (1.1.1.1) on DC B LTM instead on DC A LTM, as 1.1.1.x is the VIP range for DC A, by the time i realised my mistake and deleted the wrongly created LTM config on DC B and corrected it by creating 1.1.1.1 on DC A LTM ,

 

now strangely GTM has already discovered that VIP and still thinks 1.1.1.1 belongs to DC B as this still shows under GTM - Servers - LTM B - virtual servers (tab) , although i have correctly created it on DC A LTM by creating it there ,

 

how do i make GTM know that 1.1.1.1 VIP belongs to DC A than DC B ,

 

virtual server discovery setting is set to enabled (no delete )

 

any advice/help much appreciated

 

thanks in advance solmon
