Multiple MinArea, No-Grid and Spacing Errors

Using Encounter 13.2

Defined .capTbl, .tch, .lef files, defined timing and other settings in viewdefinition. Got the design placed and routed. Once I start checking the design with verifyGeometry I see hundreds of thousands errors of different type like:

Antenna

MinArea

No-Grid

OffGrid

Spacing

Short

Using the following commands did not help:
setOptMode -fixDRC true
optDesign -preCTS


Then I used these commands:

verifyTracks
generateTracks 
globalDetailRoute

Now the amount of errors after verifyGeometry check reduced to:

18 MinArea errors

171152 No-Grid errors

239 Spacing errors

So I see some improvement but I cannot get it any better yet. Those >170k MinArea errors and 239 Spacing errors tell me that something is wrong maybe with the flow or with the way how the tool interprets constraints. But I am not sure what exactly could be wrong.

The LEF files I am using are from the manufacturer and as they say were tested on many designs (the IBM 7RF Kit). So, I am assuming something is wrong on my side or in the way how I configure something.

Anyone has some ideas where else would be worth looking at?
