This indicates that whoever originally brought the motion withdrew it and the case was stricken (removed) from the call. The entire case has been dismissed, according to the order the judge gave you and the bank will have to refile. That is not irregular. Courts will dismiss cases which are ignored by the parties, especially if by the plaintiff.
If you were named in the proceedings or you filed your appearance, you should have been notified.
It does not appear that the case has been dismissed entirely from what you have indicated, since a Motion to Vacate has been filed. The bank is entitled to re-notice the Motion and present it to the Judge, assuming the original motion was filed within thirty days of the original dismissal. Once a proper motion is presented, the case can in fact be reinstated without re-filing.
A motion to vacate is a petition of the Court to change a previous order or judgement. A strike from call simply means that on that particular docket of the Court, for any number of reasons, this case, nor its participants are expected by the Court to be heard.
Be careful that you do not have several actions going on and perhaps are merging two unrelated actions. This can happen in foreclosure actions when there is one property which has been used as collateral for different loans from different lenders.
